Remove namespaces from Xpath expression

I need a way to remove namespaces from an XPath expression, for example if it goes something like this:

/ns1:ElementOne/ElementTwo/ns2:ElementThree

he should become

/ElementOne/ElementTwo/ElementThree

Namespaces can be different in XPath (ns1, ns2 in the above example) and can be applied at the beginning of the Xpath, for example

ns3:ElementFour

Regex? Any ideas?

Thank!

The regex matches the namespace format:

[\w]+:

EDIT:



For the ancestor part, you can use the updated regex:

[\w]+:(?!:)

So the final solution is doing this: it looks for the previously declared structure with the entire alphanumeric + underscore character, followed by the ':' character, not followed by the second: character. Hope this helps.

Don't know the format of the xpath names, but the xml spec seems fuzzy to me about using colons as a namespace separator and a valid name character that should be accepted by processors. Although colons should only be used as a namespace separator.

So minus the confirmation of the unicode encoding is

To match the last colon:



[A-Za-z_:][\w:.-]*(?<=:)

To match the first colon:

(?:[A-Za-z_][\w.-]*|):
