I have a string containing a mix of Chinese and
Latin characters, eg *|.Z'J%R+,H1N1,y7PZL.
I wish to return a nodeset containing the following kind of structure:

*|.Z'J%R+, H1N1 ,y7PZL

Where H1N1 falls into the BasicLatin unicode character block and the other two strings can be categorized as CJKUnifiedIdeographs.

Given http://en.wikipedia.org/wiki/Basic_Latin_unicode_block defines the characters up to the tilde, this can be done with a character range.

Can anyone suggest the cleanest way to do this using XSLT 2?

I like Michael's and David's suggestion better to use Unicde classes, but below is what I threw together quickly.

T:\ftemp>type tom.xml
T:\ftemp>call xslt2 tom.xml tom.xsl
<?xml version="1.0"
T:\ftemp>type tom.xsl
<?xml version="1.0" encoding="US-ASCII"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:template match="text()" priority="1">
  <xsl:analyze-string select="." regex="[!-~]+">
      <latin><xsl:value-of select="."/></latin>
      <other><xsl:value-of select="."/></other>

<xsl:template match="@*|node()"><!--identity for all other nodes-->
    <xsl:apply-templates select="@*|node()"/>


T:\ftemp>rem Done!
