'OR' operator in XPath predicate?

Question

What is the XPath expression to select elements with type=\"application/rss+xml\" OR type=\"application/atom+xm

Answer 1

use:

link[@rel='alternate'][@type='application/rss+xml' or @type='application/atom+xml'] 

see http://www.w3.org/TR/xpath/#NT-OrExpr

You could also use union to accomplish this

link[@rel='alternate'][@type='application/rss+xml']|link[@rel='alternate'][@type='application/atom+xml']

but or will do.
