Parsing XML with selectors in IE8-

Question

I am currently parsing through a WMS Capabilities XML file using selectors and this works great, nice clean code solution.

However I have stumbled across an issue with IE8- (Chrome, Safari, Firefox etc all working perfectly)

$.get(capabilitiesUrl, function (data) {
  $("WMT_MS_Capabilities Capability Layer Layer Name",  $(data)).not("Style Name").each(function (i) {
    layerNames[i] = $(this).text();
  });
});

This will successfully populate my array of layerNames in the decent browsers.

In IE9+ data is type of [Object, Document]

However in IE8- the type of data is a type of IXMLDOMDocument2 which I can't parse with the selector query.

The IXMLDOMDocument2 is also read only causing sizzle to throw an exception on:

outerCache = elem[ expando ] || (elem[ expando ] = {});

as it will try to run through elem[ expando ] = {} which fails as the IXMLDOMDocument2 is read only. With a Object doesn't support this property or method error.

Is there a way for me to populate my layerNames array using selectors or am I chasing the impossible?

Answer 1

Figured this one out.

If you use the .find() instead of the find in method it will parse properly in IE8-

Then I still had the issue of the .not() causing the exception in sizzle.

I solved this by instead of using the jQuery API of .not() to using the :not() selector.

The solution is as follows:

$(data).find("WMT_MS_Capabilities Capability Layer Layer Name:not(Style Name)").each(function (i) {
  layerNames[i] = $(this).text();
});
