[xsl] Escaping single-quotes - an old chestnut I suspect but won't respond to any amount of Googling...

[Matt Poff <matt.poff@xxxxxxxxxxxxxxx>]

Hi,

I have an XSLT file which is generating a number of SQL statements from 
an XHTML file (output method is set to "text"). I need to escape 
apostrophe and quote characters in text nodes and have tried using the 
code below:

   <xsl:function name="hf:escapechars" >
       <xsl:param name="currnode" />
       <xsl:variable name="apos" select='"&apos;"' />
       <xsl:variable name="quot" select="'&quot;'" />
       <xsl:variable name="backslash">\</xsl:variable>
      
       <xsl:value-of 
select="replace($currnode,'$apos','concat($backslash,$apos))"/>
   </xsl:function>

This generates "Description: E Invalid replacement string in replace(): 
\ character must be followed by \ or $". How can i successfully escape 
the backslash so it will output?

Thanks for you help,
Matt
