xpath expression could not find function matches [message #661235]

Hi,

Using helios, sr2, EE package.

Need to use the XPATH expression evaluator to verify xpath expressions. It's been working great for simple expressions, but now I need to do some pattern matching.

When I try to use matches('abcd', 'abcd') or matches(//mynode, 'someString') I get:

Could not find function: matches

If I try fn:matches('abcd', 'abcd') the error message goes away but I get the <No Matches> result instead.

Is the evaluator in fact working with XPATH 2.0?
How can I determine that?
And, how can I use helios to evaluate expressions with pattern matching?

thanks !

You can switch the XPath expression view, to use XPath 2.0, by default it using XPath 1.0. To do this open the XPath View, and select the View Menu, then select Processors and the XPath 2.0.

Then you can use any XPath 2.0 expression. Underneath the covers this will use the PsychoPath XPath 2.0 processor which is 99.9% conformat to the core specification and is also XML Schema Aware.

Hope this helps.
