tips for extracting a specific attribute value from an XML document

Within my C program, I am working with the following XML data:

<apStats><command chart_num="0">750</command><command chart_num="1">400</command></apStats>

.

$.ajax({
    type: "POST",
    dataType: "xml", 
    url: getUrl('/GetPeriodicStats/'), 
    data: XML.innerHTML,//stats_requests,
    success: function(c){

$(c).find('command').each(function(){
              //I need to find the value of the command element with attribute chart_num="0". What code should I use here?
                });
            });

I have included my question within the code.

Answer №1

Forget about loops, simply utilize the attribute selector to retrieve the text content

$(c).find('command[chart_num=0]').text()

Answer №2

var xmlData=fetchXMLData("books.xml");

var nodeList=xmlData.getNodeListByTagName('book');

for (index=0;index<nodeList.length;index++)
{
displayCategory(nodeList[index].getAttribute('genre'));
displayBreak();
}

Answer №3

If you're looking to locate the attribute named "chart_num", consider giving this code snippet a try:

$.ajax({
  type: "POST",
  dataType: "xml",
  url: getUrl('/FetchStatistics/'),
  data: XML.innerHTML,//stats_requests,
  success: function(response) {
    $(response).find('data').each(function(index) {
      // Check for the value of data with attribute chart_num="0"
      if ($(this).attr("chart_num") == "0") {
        alert("Chart 0 was found.");
      }
    });
  }
});
