Q:

XPath for href link

I got for example 
<a href="target.php">News</a>
<a href="more.php">More</a>

What would be the most efficient way of extracting the href based on the value between <a></a> (the atomic data) with XPath

A:

Question interpretation:

"Most efficient" is taken to mean in a programmer's time sense, not
in a performance sense.
"The value between" is taken to mean the string between the a tags.

This XPath selects all a elements,
//a

This XPath selects all a elements whose string value is "News":
//a[.='News']

This XPath selects all href attributes of all a elements whose string value is "News"1:
//a[.='News']/@href
