Re: [xsl] Processing two documents, which order?

[Wolfgang Laun <wolfgang.laun@xxxxxxxxx>]

I've been using expressions such as

<xsl:variable name="prefix"    select='"(^|\W)"'/>
<xsl:variable name="suffix"    select='"($|\W)"'/>
<xsl:variable name="pattern"   select="concat($prefix,$property,$suffix)"/>

Notice that
a) the hyphen is included in the set of stoppers, and
b) that you have to handle the cases  0word$, \Wword$, ^word\W and
\Wword\W separately so as to not lose a character matching the \W.

I think that the hyphen can be excluded by a character class
subtraction, but I'll have to study the syntax some more.

-W
