xpath2.js's Issues

Reg usage

Hi,
can you please let me know on how to include these files to work on XPath 2.0 expressions?
Thanks,
Jeya

How to get a min.js of this?

Hello,

Great library! How can I get a copy-paste-able version of this library minified? Breaking it up into many files is not practical for my use case (Chrome developer console).

Thanks!

Use a custom function in xpath

Hi,

I would like to use a custom function in xpath, but I don't see any clear documentation on how to do that.

Let's say that I want to use a custom match for regular expressions. How can I write one?

I looked at StaticContext, but it is not clear for me.

Thanks,
Alex.

regular expressions in xpath 2.0

Hey. Is there support for regular expressions in your library?
I tried:
document.evaluate("//*[matches(@Class, 'ars')]", document, null, XPathResult.ANY_TYPE, null).iterateNext();

error:
Uncaught DOMException: Failed to execute 'evaluate' on 'Document': The string '//*[matches(@Class, 'ars')]' is not a valid XPath expression.

Thank you

Is this implementation of XPath 2.0 complete?

This looks like a very interesting project. Before looking into this deeper, is there anything missing in the implementation?

processing-instruction('foo') paths produce parse error

It seems that the engine is not parsing/executing processing-instruction('foo') paths properly (i.e. PIs with a custom name). I noticed the tests for this are commented out. Is this by design?

Example snippet crashing: domClasses missing in xmldom

I'm trying to use your library with my nodeJS application, but when I try to use the snippet you have on your front page (README.md page is the one I'm referring to) I cannot access to the domClasses attribute from the xmldom library.

I've check I'm using the latest version of the xmldom (0.1.22) and the latest of your library too (0.3.2)

Anything that I'm missing? Something have change that makes your snippets unusable?

Thx!

Missing reference to cXSUntypedAtomic in XSInteger.js

Hi Sergey,

I have found one little bug in your library. Within a file XSInteger.js in method cXSInteger.cast you have used unreferenced class cXSUntypedAtomic.

so only needed to solve of this problem is add one line of code with reference to it on top of this file.

var cXSUntypedAtomic = require('./../XSUntypedAtomic');

thank you in advance

fn:string-join() fails if missing second parameter

The Spec explicitly indicates two signatures:

fn:string-join($arg1 as xs:anyAtomicType*) as xs:string
fn:string-join($arg1 as xs:anyAtomicType*, $arg2 as xs:string) as xs:string

If I pass an xpath like the following: fn:string-join(fn:reverse(fn:tokenize(fn:replace(/Row/IBAG, "(.)", "$1 "), "\s+"))) it will fail unless I explicitly add an empty string for the second parameter fn:string-join(fn:reverse(fn:tokenize(fn:replace(/Row/IBAG, "(.)", "$1 "), "\s+")), "") .

As stated in the spec:

The effect of calling the single-argument version of this function is the same as calling the two-argument version with $arg2 set to a zero-length string.

The function returns an xs:string created by casting each item in the sequence $arg1 to an xs:string, and then concatenating the result strings in order, using the value of $arg2 as a separator between adjacent strings. If the value of $arg2 is the zero-length string, then the members of $arg1 are concatenated without a separator.

Replace function returns boolean rather than string
