This is always kinda difficult because of the definition of white space. XSLT 2.0 lets you do useful things with regular expressions and the Unicode space character category, \p{Zs}, so you can replace all sequential white space with one regular space, but of course line feeds aren't spaces so you have to add that in -- <xsl:template match="text()"> <xsl:value-of select="replace(.,'[\p{Zs}
]+',' ')"/> </xsl:template> which won't strip the trailing space. It might still qualify as having to re-write normalize-space(). The XSLT 1.0 solution involves substring() and string-length(); you saw off the last character, normalize the substring of everything but the last character, and concat() them back together. This has the disadvantage of leaking non-breaking spaces. -- Graydon
