XSLT substring-after
<p>I have string:  <code>$number=Twentyone one two three</code>. I need to fetch the value after the string <code>one</code> that is <code>two three</code>. I have written the below xslt query: </p>

<pre><code>substring-after($number,'one') 
</code></pre>

<p>which returns <code>one two three</code>. </p>

<p>What is the the query to exactly match the whole string only with <code>one</code> and then return <code>two three</code>?</p>
