Question

I want to extract tags in XML which contains attribute condition as name="var". But I don’t know which element has got this attribute condition so can I use following XQuery:

<ab>
    <c name="var">
        <d name ="var">
            <e>
            </e>
        </d>
        <f>
        </f>
    </c>
</ab>

XQuery:

doc('abc.xml')//ab/*[@name="var"]

I have XML generated by CLANG which has no values for tags but everything is present as attribute only.

Answer 1

You’re currently select all elements in abc.xml which are children of an element called <ab> and have the given attribute.

As you want “extract tags in XML which contains” and the document provided I guess you actually want to query all elements within top-level-element <ab>, which would be written as

doc('abc.xml')/ab//*[@name="var"]

and return both element <c> and <d> with their respective child nodes.

<c name="var">
  <d name="var">
    <e/>
  </d>
  <f/>
</c>

<d name="var">
  <e/>
</d>
