It seems that the DOM parsed 'on the fly' isn't ready for querying.

When doing something weird like:

var xml = $('Hello World!Bye World!');
$(xml).appendTo("body");

then the

alert($("p").text());  // without context

works !

That is not correct. You can build a jQuery instance from a xml object
and use the various jQuery query options to search through the xml tree
directly.


Step, have you tried the method find?

$(xml).find('building').each(function()
{
alert($(this).find('city_id').text());
});

hth,
Tim.

the first try will not work with latest jquery, as xpath is now into a
seperate plugin. So stick to your second try. Also, make sure you search
your xml when the xml is actually loaded, so in the ajax function callback

$.ajax({//your params here}, function(xml,status){
if(status=='success'){
$('building', xml).each(function()
   {
   alert($("city_id", this).text(););
   });
}
});

cheers,

Actually if it doesn't have to be part of the DOM assuming you are
passing in a context as the second parameter of $() which the original
author is.

I don't use the xpath plugin so I'm not sure about that but the second
attempt you said failed worked for me.  I got 3 alert boxes with '1',
'2', '3' just as I expected.  Here is my test case.

  function doIt() {
$.get("jquery_xml_load.xml", function (xml) {
  $("building", xml).each(function () {
alert($("city_id", this).text());
  });
});
  }

  $(document).ready(function() {
$("button").click(doIt);
  });

  
  
Do It
  


The xml file is a copy and paste of what you put in your post.  I
think your problem is somewhere other than what you posted.

Hope that helps.

[jQuery] Re: Parsing XML using jQuery

[Dave Stewart]

Not sure if this is the best reply, but in order to access the
structure, it has to be part of the DOM, so best to inject in into a
placeholder first:

$('#placeholder).html(xml) // probably need to kill the xml
declaration first

Then you can use jQuery to traverse the tree.
