lixml2 C xpath fails with "invalid expression"

Question

I use libxml2 in C application to parse XML files.

I get an error when I search for XPath with special character '$'.

Here my code :

xmlXPathExpression("//mytag/foo$");

And I get error "Invalid expression".

I tried to encode speical characters like this :

xmlXPathExpression("//mytag/foo&#36;");

But I get same error.

Any help ? Thanks.

I do not see $ listed as a valid character in element name: XML 1.0.

So i can't use any special character in xml element name ? – TheFrancisOne Jul 27 '12 at 14:05
You can use thousands of different characters in an XML element name, but not currency symbols. – Michael Kay Jul 27 '12 at 21:50
