Given a node $n, you can find the value of its ID attribute if it has one
using
$n/@*[id(.) is $n]

Subject: Re: [xsl] Finding the ID attribute of an XPath from XMLSchema
Below is a snippet from the XMLSchema
<xs:complexType name="nameType">
<xs:sequence>
<xs:element minOccurs="0" ref="desig"/>
</xs:sequence>
<xs:attribute ref="dest" use="required"/>
<xs:attribute ref="id"/>
<xs:attribute ref="garageid"/>
<xs:attributeGroup ref="xlink:XLINKATT1"/>
</xs:complexType>
<xs:attribute name="id" type="xs:ID"/>
this means that in the XML, the nameType node can be
identified by the id attribute as xs:attribute name=id is
mapped to XS:ID.
Likewise there can be many nodes in the XML that has ID
associated to it.
<xml>
<root>
<somenode>
<nameType id="2" attrib2="34">text</nameType> <nameType
id="3" attrib2="34">text</nameType> <nameType id="4"
attrib2="34">text</nameType> </somenode> <anothernode
attrib5="55"/> </root>
In the XML, I perform some kind of XQuery and I get the
output as root/somenode/anothernode/nameType.
Once I get this node, I should be able to find if there is an
ID attribute defined for this node in the XSD.
In the above case, the id attribute in the nameType tag is
the attribute as per the XML Schema.
So I need the output as id for the xpath
root/somenode/anothernode/nameType
Hope I have explained it better!
Well what I thought was this way as a solution 1. Parse the
XMLSchema 2. Make a map of XPath as key and the id as attribute.
3. Once I get the xpath from xquery, check the map to find
the id 4. But parsing XMLSchema and mapping is not that simple either

For each XPath I need to know what is the ID attribute

I know that in XMLSchema there is an XS:ID Attribute. I
would like
to know if there is a way to find the ID associated from the
XMLSchema for an XPath in the XML.
Did I confuse everyone?
You certainly confused me. Show us your source document and tell us
what you want your output to look like.
