Below is a snippet from the XMLSchema

<xs:complexType name="nameType">
			<xs:element minOccurs="0" ref="desig"/>
		<xs:attribute ref="dest" use="required"/>
		<xs:attribute ref="id"/>
		<xs:attribute ref="garageid"/>
		<xs:attributeGroup ref="xlink:XLINKATT1"/>
<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.

<nameType id="2" attrib2="34">text</nameType>
<nameType id="3" attrib2="34">text</nameType>
<nameType id="4" attrib2="34">text</nameType>
<anothernode attrib5="55"/>

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

You certainly confused me. Show us your source document and tell us what you
want your output to look like.
