I have this element as my context element:
<p>{{image_100}}GEO_AS_MC_M01_T02_05.eps{{/image}}</p>
And I want to get the "GEO_AS_MC_M01_T02_05.eps" using analyze-string, where the value
"image_100" could have any value where "100" is in this example.
I can't work out the way to escape the curly braces in the @regex value so my
match works (or I can't work out what else I might be doing wrong).
Oxygen's regex search gives me the correct result with this:
\{\{image_.+}}([^{]+)\{\{/image}}
But this attempt in XSLT 3 does not work:
<xsl:analyze-string select="." regex="\{{\{{image_.+}}(.+)\{{\{{/image}}}}">
In that the non-matching substring is the entire selected string,
What regex or escaping detail am I missing?
Part of the problem I think is that the "regexp" attribute of
"xsl:analyze-string" allows attribute value templates so you either have
to double curly braces or better declare your pattern as a parameter or
variable before the element e.g. using Michael's suggestion
<xsl:param name="pattern"
as="xs:string">\{\{image_[^}]+\}\}([^{]+)\{\{/image\}\}</xsl:param>
and then you can use
<xsl:analyze-string select="." regex="{$pattern}">
