Subject: Re: [xsl] How to compare two QName values in an XML Schema? From: Martin Honnen <Martin.Honnen@xxxxxx> Date: Fri, 08 Apr 2011 18:14:04 +0200 |
Hi Folks,
Below is an XML Schema, containing two simpleTypes. The second one references the first.
I want an XPath expression that compares the second simpleType's reference to the name of the first simpleType:
/xs:schema/xs:simpleType[1]/@name eq /xs:schema/xs:simpleType[2]/xs:restriction/@base
That returns False. I want it to return True.
I figured the reason it's returning False is because it is comparing the string "elev:BostonAreaSurfaceElevation" against the string "EarthSurfaceElevation". Yes?
I want it to do a comparison of QNames, not strings. So I type-cast the values:
xs:QName(/xs:schema/xs:simpleType[1]/@name) eq xs:QName(/xs:schema/xs:simpleType[2]/xs:restriction/@base)
But that gave me this error:
Casting from xs:unTypedAtomic to xs:QName can never succeed.
Why?
What's the correct way to do the comparison?
