I need a way to implement the function matches() from XPath 2.0 with functions from XPath 1.0

I have the following piece of code:

root="//valueExpression[matches(self::*,'p开发者_开发技巧attern')]/.."

But I can only use XPath 1.0 and I get an exception for the function matches(). Can you please help me with a solution using only functions from XPath 1.0 ?

Generally, this can't be done just using XPath 1.0.

However, there is a set of standard XPath 1.0 functions that you can use for string processing:

• substring()
• substring-before()
• substring-after()
• translate()
• normalize-space()
• string-length()
• count()
