[xsl] matches() method in XPath 1.0

["Manuel Souto Pico terminolator@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Dear all,

I have a simple question, hopefully someone can help.

Given some nodes like this:

<text>Some text.</text>
<text>foo.svg</text>

in XPath 2.0 I can match the ones (like the second) that contain a file
name with something like

//text[matches(text(), '[^\s]*\.(svg|png|jpg)')]

That should match the second text node, and not the first.

I am looking for something to achieve the same purpose in XPath 1.0, even
if it's using something like ends-with instead of regex.

Why XPath 1.0? I'd love to use version 2.0 but this is for using the ITS
data categories, which seem not to be compatible with XPath 2.0

Could someone have an idea?
Thank you so much.
Cheers, Manuel
