This is doable with an XPath query. Let's assume you have a variable
called doc that contains the XML document, and then you could use this
expression:

  doc["header/data[@label='GICSIndustry']

The result will be the *list* of matching "data" elements. So if
there's no match, it will be an empty list. (If there's exactly 1
match, the result also can be used as a single value which is the same
as the first item of the list.)
