Re: tokenize a string with escaped spaces

Double-quotes in an XML attribute value should be written as `"`. Also
remember that this is an attribute value template, so curly braces need
special treatment.

I often write such things as

<xsl:variable name="regex">\S*('[^']*')?("[^"]*")?</xsl:variable>
<xsl:analyze-string regex="{$regex}">....

which reduces these problem (fortunately & and < aren't metacharacters in
regular expressions).
