MySQL Bugs: #18170: XML: ExtractValue(): XPath expression can't use QNames (colon in names)

Bug #18170	XML: ExtractValue(): XPath expression can't use QNames (colon in names)
Submitted:	12 Mar 2006 20:45	Modified:	5 May 2006 17:12

Status:	Closed	Impact on me:	None
Category:	MySQL Server: XML functions	Severity:	S3 (Non-critical)
Version:	5.1.7/5.1.8 BK	OS:	Windows (win xp pro/Suse Linux 10)
Assigned to:	Alexander Barkov	CPU Architecture:	Any

Description:
The ExtractValue() functions allows one to extract data from an XML fragment using an XPath expression. The XPath expression should be able to contain fully qualified names, but this leads to the following error:

ERROR 1105 (HY000): XPATH syntax error: ':<tagname>)'

In other words, the parser sees it as an error to have a colon inside a name. 
This makes it totally impossible to work with namespaces

How to repeat:
mysql> select extractValue('<ns:element xmlns:ns="myns"/>','count(ns:element)');
ERROR 1105 (HY000): XPATH syntax error: ':element)'

Suggested fix:
Allow the XPath to contain fully qualified names

just updated the title
