Getting attribute of xml child nodes in jQuery

Question

I had to amend this question because I left out a piece of code that breaking things. I only want to look at the images for a certain church.

xml file:

<churches>
<church>
        <data-name>germanevangelical</data-name>
        <name>German Evangelical</name>
        <address>501 Elm St.</address>
        <opened>1887</opened>
        <neighborhood>East</neighborhood>
        <region>East</region>
        <architecture>Gothic</architecture>
        <denomination>Evangelical Lutheran</denomination>
        <closed>2006</closed>
        <image caption="Mary Smith">image_1_forweb.jpg</image>
        <image caption="Mary Smith">image_2_forweb.jpg</image>
        <image caption="Mary Smith">image_3_forweb.jpg</image>
</church>
... (more church nodes)
</churches>

I want to access the image captions with jQuery.

Here is my code, but it's returning "undefined" for the captions:

var cName = 'germanevangelical';  
$.ajax({
              type: "GET",
              url: "churchdata.xml",
              dataType: "xml",
              success: function(xml) {
                var name = $(xml).find("data-name"); //get church names from xml file
                $(name).each(function(id, item) {
                    if ($(item).text() == cName) { //find the right church in the xml file
                        $(item).parent().find("image").each(function(id, node) {
                            console.log('id: ' + $(node).attr('caption'));//undefined
                        })
                    }//end if right church in xml file
                })
              }
            });

Can anyone see what I'm doing wrong please?

Answer 1

There is a very small mistake in your ajax code while parsing, use $xml instead of $(xml) while finding "data-name". Please check below code.. Try to run your page in chrome and check if any errors in the developer tools, if there is any errors it wont work.

var cName = 'germanevangelical';  
$.ajax({
type: "GET",
    url: "churchdata.xml",
    dataType: "xml",
    success: function (xml) {
    var xmlDoc = $.parseXML(xml),
    $xml = $(xmlDoc);
    var name = $xml.find("data-name"); //get church names from xml file
        $(name).each(function(id,item) {
              if ($(item).text() == cName) {
                $(item).parent().find("image").each(function(id,node) { 
                    console.log('id: ' + $(node).attr('caption')); //undefined
                });
               }
        });
      }
 });

$.parseXML() is not necessary, where dataType at $.ajax() is set to "xml" an XMLDocument should be returned as xml at success of $.ajax() call.

Note also, missing closing ) at .each() calls at javascript at Question.

$.ajax({
  type: "GET",
  url: "churchdata.xml",
  dataType: "xml",
  success: function(xml) {
    console.log(xml);
    var name = $(xml).find("data-name"); //get church names from xml file
    $(name).each(function(id, item) {
      $(item).parent().find("image").each(function(id, node) {
        console.log('id: ' + $(node).attr('caption'));
      })
    })
  }
});
