Support for XMLDocument as well as document? #7

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
My applications get XML documents from HTTPRequest.responseXML and DOMParser.

How difficult is it to extend your solution so that your solution for document 
also works on these other objects?

For XML documents, IE provides native support for XPath through the selectNode 
and selectNodes methods.

It wouldn't be too hard for us to delegate to that method, so we will leave 
this open as a feature request.

For info: As you know there has been a substantial change in XML support by MS 
for IE over recent versions. The new HTTPrequest/XML implementation supports 
XML basic functions but has  big gaps when you try and use namespaces whereas 
the old native form does not.  You get this stupid (thanks yet again from 
Microsoft) position that they introduced the new XML object but it doesn't 
support everything most other browsers do according to international standards.

But the response actually does not address the question - for the question does 
not relate specifically to Internet Explorer.

Does document.evaluate not function correctly on non-IE browsers? This library 
exists primarily because of IE's lack of native support for XPath, though it 
happens that there are a couple other use cases as well.

Yes

IE is a mess.

All browsers including recent IE have .evaluate method.  

Under new IE evaluate does not work with namespaces and so it is useless for 
searching via xpaths that have them and so we have to force IE to revert to 
native mode.

My specific point also is that there are several ways of getting an XML object, 
not just 

new DOMParser().  etc

And it would be really useful for your stuff to apply to all of them

For example the XMLhttprequest.responseXML property which we use very very 
heavily 

Hope this helps

I am using this lib as well for evaluating documents.

It is a rhino+env.js setup, where env.js misses a working xpath implementation

I am adding the evaluate method to document out of a DOMParser and it works as 
long as no namespaces are involved.

+1 for XML support.

to be more precise, namespace works but only if the xpath queries from the 
document node, not from a child node.

My use case for wgxp is to extend it with custom XPath functions and use if for 
XML Documents. Since native implementations cannot be extended, I have to use a 
JS library. 

If I understand the above correctly, this library will not have proper 
namespace support for XML Documents. 

Any plans to add this? Would it be a significant effort?
