How to select two attributes from the same node with one expression in XPath?

Question

For example:

//person[@id='abc123']/@haircolor|/@weight"

PS. there are lots of "person" records

Solution

Try this:

//person[@id='abc123']/@*[name()='weight' or name()='haircolor']

If you're using an XPath 2.0 processor, you may also use a prettier option:

//person[@id='abc123']/(@haircolor|@weight)`

//person[@id='abc123']/(@haircolor|@weight) is valid XPath - but you need an XPath 2.0 processor to run it.

@Michael - Thanks, good to know! Unfortunately, I usually deal with the older version. Anyway, I'll take your word for it and update the answer. Thanks again.

@Kobi - is it also possible to concatinate the output? Because running my XPath expression based on your answer leads me to a double output.

[Kobi]

@Vilius - It shouldn't duplicate anything, as far as I know. I'm not sure what you mean by "concatinate"... It is probably best is you ask a new question with the exact the details.
