How to Trim in xslt?

Question

I want to trim whitespace left and right in :
<xsl:value-of select="Datas/Data[@key='Name']/string"/>

How can I do that?

Answer 1

normalize-space(Datas/Data[@key='Name']/string) might suffice, it will trim white space and the start and end. It does however also collapse any white space in between to a single space, I don't know whether you want that.
