[erlang-bugs] [BUG] xmerl does not support contains(string, string) XPath function

[Balint Reczey (IJ/ETH)]

Hi,

The xmerl_xpath module summary says that it implements the whole XPath language, but it seems 
that the contains() string function ( http://www.w3.org/TR/xpath#function-contains ) is missing:

13> xmerl_xpath:string("//foo[contains(@bar, 'oe')]",element(1,xmerl_scan:string("<foo bar=\"Joe\" />"))).
