Re: XPath Query Fails

You may want,

(//foo[1]//bar)[2]
or
//for[1]/descendant::bar[2]

Both are same. However,

//foo[1]/bar[2]

means,

//foo[1]/descendant-or-self::node()/bar[2]

both are same. That means the second child of the parent of <bar>, i.e. <c>.
If there are lots of <c>s, and if they have more then one <bar>, the last
two xpath will select all of the second <bar>s. The abbreviated operators
sometimes can be confusing. Use full path.
