[jira] Updated: (XALANJ-1912) match="and" causes error - doesn't comply with XPath spec section 3.7

Santiago Pericas-Geertsen updated XALANJ-1912:
----------------------------------------------

    Attachment: xpath.lex.patch

I'm attaching a patch to solve this problem. It is a tricky one because the lexer is created using JLex. It should, however, work in most cases. XSLTC is now able to parse expressions such as "and and and" or "preceding-sibling and child". We need a reviewer for this patch.

> Trying to compile a stylesheet with 'template match="and"' or with 'template
> match="or"' causes an error. The compiler reports a syntax error. Probably it
> interprets the expression "and" as an OperatorName.
> However, the XPath spec in section 3.7 (http://www.w3.org/TR/xpath#exprlex)
> states clearly that a token must not be recognized as an OperatorName unless
> there is a preceding token (other than @, ::, (, [, , or an Operator).
> In the expression "and" there is only one token (namely "and"). There is no
> preceding token, so the token "and" must NOT be recognized as an OperatorName!
> Instead it should be recognized as a NameTest, matching an XML element named "and". 
> The same applies to "or".
