Remember that the attribute is an attribute value template so curly
braces are special.

Best is probably,

<xsl:variable as="xs:string" name="regex"
  select="\{\{image_100\}\}GEO_AS_MC_M01_T02_05.eps\{\{/image\}\}" />

<xsl:analyze-string regex="{ $regex }" select="." />

I sometimes write [{] and [}] for braces - and the same for parens - as
it's hard to remember which regex syntaxes treat \{ as special and
which are the other way round!
