Styling a nested XML element with XSLT?

I’m a print designer working on a travel guide that we recently started managing with XML-tagged content and XSLT styling. It mostly works, aside from this one small issue that has driven us to wit’s end! We have some sub-attraction listings that should appear as “child” listings that we can style differently in InDesign layout, and they’re noted in the XML by noting a value for their “parent” attraction in the MainAttraction tag.

My understanding is that we need the .XSL to notice whether there’s a value in the MainAttraction tags, and if there is, then to pull out the elements associated with that attraction to go under a different container tag so we can style them differently. I just haven’t had any luck writing syntax for this that works after doing some basic training and Googling around forums.

Here's what I'm experimenting with, which pulls in everything correctly except for sub-attractions (they're listed within the Attraction tags for their associated parent listing):

So what do I do here to make it so sub-attractions (attractions with a value int he MainAttraction field) can get pulled into new container tags? I understand that we want to create a new template for SubAttractions, but I don't know how to get only the desired elements into it. I'd greatly appreciate help in finding something to plug in here if it's not too difficult for someone more experienced.

I have a numeric string column in oracle with or without leading zeros samples:

00000000056
5755
0123938784579343
00000000333  
984454  

The issue is that partial Search operations using like are very slow

select account_number from accounts where account_number like %57%

one solution is to restrict the search to exact match only and add an additional integer column that will represent the numeric value for exact matches.
At this point I am not sure we can add an additional column,
Do you guys have any other ideas?

Is it possible to tell Oracle to index the numeric string column as an integer value so we can do exact numeric match on it?

for example query on value :00000000333
will be:

select account_number from accounts where account_number = '333'

While ignoring the leading zeros.
I can use regex_like and ignore them, but i am afraid its going to be slow.

Get Cell Value with column name in Php Excel

This is my excel sheet it has got lots of columns but i'm breaking down for ease in understanding the question

I'm reading Excel Sheet using PHP Excel and using rangeToArray() which give me all row from excel but i want the output as

Column as Key:Cell Value as Value

Currently I'm get output as

Col Index :Cell Value

So my Question is which is that function in Php Excel which return array with Column name and it Cell value?

try {
    $inputFileType = PHPExcel_IOFactory::identify($inputFileName);
    $objReader = PHPExcel_IOFactory::createReader($inputFileType);
    $objPHPExcel = $objReader->load($inputFileName);
} catch(Exception $e) {
    die('Error loading file"'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage());
}
//  Get worksheet dimensions
$sheet = $objPHPExcel->getSheet(0); 
$highestRow = $sheet->getHighestRow(); 
$highestColumn = $sheet->getHighestColumn();
for ($row = 2; $row <= $highestRow; $row++){ 
    //  Read a row of data into an array
    $rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row,
                                            NULL,
                                            TRUE,
                                            FALSE);
    printArr($rowData);
    printArr("-------");

}

I get output as

Angular datatable add row keep search value / display selected record

I have an angular datatable that is displaying "multiple" pages of 10 records each. If I use the search box to only view selected records and add a new row the table completely refreshes. The value in the search box is reset and my view goes back to the first page of records. Is it possible to maintain the value in the search box?

Similar but different. I have a radio button to select a record in the table. Is it possible when the table is redrawn to show the page with the selected record and not the first page.

c++ not recognizing negative number as a number entered

In a program I have to write for class, I can not get the code to read a negative from cin to increment a variable by one.

int input;

while (input != 9999)
{
    sum += input;
    count ++;
}

There is other code that counts the number of pos, neg, and zeros entered. this is the only place count is used. so if I enter -10 then 9999, the sum is -10 and the number of negative is 1 but count says zero. i am using dev c++ as a compiler. and windows 10

Invalid Swift Support - Files don’t match

I just re-wrote an app in Swift 2. I'm trying to upload the app to iTunesConnect (via Xcode 7 GM) for internal testing.

I wrestled with an "Invalid Swift Support" error for awhile (which has other, related questions) ... but now it's changed to something a little different.

The error from Apple now says:

Invalid Swift Support

The files libswiftCoreLocation.dylib, libswiftCoreMedia.dylib, libswiftCoreData.dylib, libswiftAVFoundation.dylib don’t match

/Payload/http://ift.tt/1XTi1Om, /Payload/http://ift.tt/1FBPwcO, /Payload/http://ift.tt/1XTi1Oo, /Payload/http://ift.tt/1FBPyBu

Make sure the files are correct (?), rebuild your app, and resubmit it.

Don’t apply post-processing to

/Payload/http://ift.tt/1XTi1Om, /Payload/http://ift.tt/1FBPwcO, /Payload/http://ift.tt/1XTi1Oo, /Payload/http://ift.tt/1FBPyBu.

I've been unable to find similar errors by searching for "Don’t apply post-processing", "Make sure the files are correct (?), rebuild your app, and resubmit it", etc.

Does anyone know how I can "Make sure the files are correct" --or-- any other recommendations? Thank you.

C# FTP Download large files

i know this is probably not the first time, this is asked. But i can't find the solution to the problem..

  private void bgftpdownload_DoWork(object sender, DoWorkEventArgs e)
    {
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftpurl + "/" + clientlabel.Text + "/data.7z");
        request.Credentials = new NetworkCredential(ftpuser, ftppass);
        request.Method = WebRequestMethods.Ftp.GetFileSize;
        request.Proxy = null;

        FtpWebResponse response = (FtpWebResponse)request.GetResponse();
        long fileSize = response.ContentLength;

        request = (FtpWebRequest)WebRequest.Create(ftpurl + "/" + clientlabel.Text + "/data.7z");
        request.Credentials = new NetworkCredential(ftpuser, ftppass);
        request.Method = WebRequestMethods.Ftp.DownloadFile;
        using (FtpWebResponse responseFileDownload = (FtpWebResponse)request.GetResponse())
        using (Stream responseStream = responseFileDownload.GetResponseStream())
        using (FileStream writeStream = new FileStream(LocationFile, FileMode.Create))
        {

            int Length = 2048;
            Byte[] buffer = new Byte[Length];
            int bytesRead = responseStream.Read(buffer, 0, Length);
            int bytes = 0;

            while (bytesRead > 0)
            {
                writeStream.Write(buffer, 0, bytesRead);
                bytesRead = responseStream.Read(buffer, 0, Length);
                bytes += bytesRead;
                int totalSize = (int)(fileSize / 1048576);
                bgftpdownload.ReportProgress((bytes / 1048576) * 100 / totalSize, totalSize);
            }
        }

            progressBar1.Value = e.ProgressPercentage;
    }

I have this code, and its working great.. until its hitting a 2 gb file on the ftp server

I can read on other forums, the value limit for (int) is = 2147483591 So the problem is off cause my byte is getting higher than limit (2147483591)

What can i do to fix this problem?

Spring cannot create filter on online server only (works fine on the localhost)

My Spring application deploys and works fine on my localhost but fails on the online server with the following exception:

}

Again, it works just fine on my localhost.

Should i implement a database or let operating system manage files(Media Library Application)

I'm writing a media library application.(Like iTunes). Users can have thousands of media files.(Some files may be small like music and some files may be large like movies) Users should do operations like search,add,remove,change info etc. fast enough. I'm trying to make a decision about how i store & retrive these files.

One way: Like itunes i can create a folder for library, in that folder i can create another folder for each artist, in each artist folder i can create a folder for each album and at last in album folder i can store music files. I'll create another file for storing information about music files(Album arts, lyrics and etc.) This way is easy to implement and manage. It will be fast also.

Second way: I can store everything in 1 file. I can use a database to store everything or i can use other methods like BinarySerialization and creating my own file type. This file type can have media file itself and it's information in it. I don't know if its possible. I don't know if it will be fast enough to extract a file and change smthng on it and storing it back.

Should i use itune's way or can you recommand another way to do it.

JQuery hide Class if other class is visible

I know this question already have asked before and i also tried the answer and it almost worked for me but there is one issue which i can't able to sort i tried plenty of ways but all in wain. This is the div i want to hide

    <div class="price-box" itemprop="offers" itemscope="" itemtype="http://schema.org/Offer">

       <p class="price"><span class="special-price" style="display: none;">
        <span class="amount">$43.50</span>
        </span>
       </p>
    </div>

when this div is not empty

<div class="single_variation"><span class="price"><span class="amount">$43.50</span></span></div>

This is what i implement

  jQuery(document).ready(function() {

    if( jQuery('.single_variation').is(':empty') ){
      alert('hi');
        jQuery('.price-box').show();
      }

});

and also

if($('.price').length){ $('.price-box').hide(); }

Is the $scope.$apply() call warranted for this scenario?

New to AngularJS (and JavaScript frankly), but from what I've gathered, explicit calls to $scope.$apply() are only needed when changes happen outside of angular's radar. The code below (pasted in from this plunker) makes me think it wouldn't be a case where the call is required, but it's the only way I can get it to work. Is there a different approach I should be taking?

index.html:

<html ng-app="repro">
  <head> 
    ...
  </head>
  <body class="container" ng-controller="pageController">
    <table class="table table-hover table-bordered">
        <tr class="table-header-row">
          <td class="table-header">Name</td>
        </tr>
        <tr class="site-list-row" ng-repeat="link in siteList">
          <td>{{link.name}}
            <button class="btn btn-danger btn-xs action-button" ng-click="delete($index)">
              <span class="glyphicon glyphicon-remove"></span>
            </button>
          </td>
        </tr>
    </table>
  </body>
</html>

script.js:

var repro = angular.module('repro', []);

var DataStore = repro.service('DataStore', function() {
  var siteList = [];

  this.getSiteList = function(callback) {
    siteList = [ 
      { name: 'One'}, 
      { name: 'Two'}, 
      { name: 'Three'}];

    // Simulate the async delay
    setTimeout(function() { callback(siteList); }, 2000);
  }

  this.deleteSite = function(index) {
    if (siteList.length > index) {
      siteList.splice(index, 1);
    }
  };
});

repro.controller('pageController', ['$scope', 'DataStore', function($scope, DataStore) {
  DataStore.getSiteList(function(list) {

    $scope.siteList = list; // This doesn't work
    //$scope.$apply(function() { $scope.siteList = list; }); // This works

  });

  $scope.delete = function(index) {
    DataStore.deleteSite(index);
  };
}]);

lifetime of a variable inside a self invoking anonymous function - function closures

I'm studying function closures from http://ift.tt/1vKs8WG

I don't understand the below code. variable add refers to a self-invoking anonymous function which returns an anonymous function. In this case, what happens to variable counter? when we call function add, what happens?

<!DOCTYPE html>
<html>
<body>

<p>Counting with a local variable.</p>

<button type="button" onclick="myFunction()">Count!</button>

<p id="demo">0</p>

<script>
var add = (function () {
    var counter = 0;    })();
    return function () {return counter += 1;}


function myFunction(){
    document.getElementById("demo").innerHTML = add();
}
</script>

</body>
</html>

in addition I dont understand why the code below does not work?

<!DOCTYPE html>

                 return function(){ semih += 5;  }
             }
             return counter += 1;}
           }
)();

function myFunction(){
    document.getElementById("demo").innerHTML = add();

Assign line colors in pandas

I am trying to plot some data in pandas and the inbuilt plot function conveniently plots one line per column. What I want to do is to manually assign each line a color based on a classification I make.

The following works:

df = pd.DataFrame({'1': [1, 2, 3, 4], '2': [1, 2, 1, 2]})
s = pd.Series(['c','y'], index=['1','2'])
df.plot(color = s)

But when my indices are integers it no longer works and throws as KeyError:

df = pd.DataFrame({1: [1, 2, 3, 4], 2: [1, 2, 1, 2]})
s = pd.Series(['c','y'], index=[1,2])
df.plot(color = s)

The way I understand it is that when an integer index is used it somehow has to start from 0. That is my guess since the following works as well:

df = pd.DataFrame({0: [1, 2, 3, 4], 1: [1, 2, 1, 2]})
s = pd.Series(['c','y'], index=[1,0])
df.plot(color = s)

My question is:

• What is happening here?
• Assuming I have an integer index that does not start from 0 or is not formed of successive numbers, how can I make this work without having to convert the index to string or reindex starting from 0?

EDIT:

I realised that even in the first case, the code doesn't do what I expected it to do. It seems like pandas matches the index of DataFrame and Series only if both are integer indices starting from 0. If that isn't the case, a KeyError is thrown or if the index is a str the order of the elements is used.

Is this correct? And is there a way to match the Series and DataFrame indices? Or do I have to make sure I pass a list of colours in the right order?

Roslyn - how to reliably format whitespace for a class

I need to format a class to ensure it's easily human readable. I have the syntax tree, the root CompilationUnitSyntax and the ClassDeclarationSyntax. I format the whitespace as follows.

root = root.ReplaceNode(classSyntax, classSyntax.NormalizeWhitespace(elasticTrivia: true));
syntaxTree = syntaxTree.WithRootAndOptions(root, syntaxTree.Options);

Before:

#region MyRegion
public class MyClass
{

    // Info about MyClass

}
#endregion

After:

#region MyRegion
public class MyClass
{
// Info about MyClass    
}#endregion

Why is the class's closing brace slammed into the #endregion?

If I run NormalizeWhitespace once more on the 'After' text, #endregion is moved back down onto its own line. Then a further call to NormalizeWhitespace moves it back up again. What is going on?

Total time in python's line profiler is strange

This is my insertion.py:

import random

#@profile
def insertion_sort(l):
    for j in range(1, len(l)):
        k = l[j]
        i = j - 1
        while i >= 0 and l[i] > k:
            l[i + 1] = l[i]
            i -= 1
        l[i + 1] = k


if __name__ == '__main__':
    l = range(5000)
    random.shuffle(l)
    insertion_sort(l)

When I run time python insertion.py, I get:

real    0m0.823s
user    0m0.818s
sys     0m0.004s

But when I uncomment the profile decorator and run: kernprof -l -v insertion.py, I get:

Wrote profile results to insertion.py.lprof
Timer unit: 1e-06 s

Total time: 7.25971 s

 8      4999         1719      0.3      0.0          i = j - 1
 9   6211255      2695158      0.4     37.1          while i >= 0 and l[i] > k:

11   6206256      2160158      0.3     29.8              i -= 1
12      4999         1959      0.4      0.0          l[i + 1] = k

My question is why total time of line profiler is much greater than the system time? I thought "Total time" of line profiler was describing how much time the function decorated with @profile was running. In my head, the output from time should be greater or at least close to line profiler. Am I interpreting the results wrong? Is line profiler adding its own time to "Total time"?
