Re: [xsl] Seek a simple XPath 2.0 expression to return union xs: simpleT

Hi Folks,

I seek an XPath 2.0 expression that returns all XML Schema simpleTypes 
containing a union with memberTypes containing the XML Schema string type. 
(Phew! Did you catch all that?)

So, the XPath should return the union simpleType in this schema:

----------------------------------------------------------------------------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>

     <xs:simpleType name="test">
         <xs:union memberTypes="xs:int xs:string" />
     </xs:simpleType>

</xs:schema>
----------------------------------------------------------------------------------

The XPath should not return the union simpleType in this schema:

----------------------------------------------------------------------------------
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>

     <xs:simpleType name="test">
         <xs:union memberTypes="xs:int string"/>
     </xs:simpleType>

    <xs:simpleType name="string">
        <xs:restriction base="xs:string" />
    </xs:simpleType>

</xs:schema>
----------------------------------------------------------------------------------

I created a horrendously complex XPath 2.0 expression. I think it works (it's 
so complex, I'm not sure). Is there a simpler XPath 2.0 expression to solve 
this problem?

Here's the ugly XPath 2.0 expression that I created:

//xs:simpleType[xs:union[@memberTypes]
        [exists(index-of(for $here in ., $i in tokenize(@memberTypes, '\s+') 
return
         namespace-uri-from-QName(resolve-QName($i, $here)) eq
            'http://www.w3.org/2001/XMLSchema' and
        local-name-from-QName(resolve-QName($i, $here)) eq 'string', true()))]]


I think there is an equality comparison for QNames

//xs:simpleType[xs:union[@memberTypes][some $type intokenize(@memberTypes, '\s+') satisfies resolve-QName($type, .) eqQName('http://www.w3.org/2001/XMLSchema', 'string')]]
