xpath expression to remove whitespace

Question

I have this HTML:

Answer 1

I. Use this single XPath expression:

translate(normalize-space(/tr/td/a), ' ', '')

Explanation:

1. normalize-space() produces a new string from its argument, in which any leading or trailing white-space (space, tab, NL or CR characters) is deleted and any intermediary white-space is replaced by a single space character.

2. translate() takes the result produced by normalize-space() and produces a new string in which each of the remaining intermediary spaces is replaced by the empty string.

II. Alternatively:

translate(/tr/td/a, ' 	

', '')
