Re: replacing a string value

Am I right in assuming that the '?' can occur at any place in the input?:

<foo> hello ? world ? foo </foo>
would translate to:
<foo> hello <img/> world <img/> foo </foo>

This stylesheet will do what you want:

<?xml version="1.0"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
version="1.0">
  
  <xsl:template match="text()" name="img-replace">
    <xsl:param name="text" select="string()"/>
    <xsl:choose>
      <xsl:when test="not(contains($text, '?'))">
        <xsl:value-of select="$text"/>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="substring-before($text, '?')"/>
        <img/>
        <xsl:call-template name="img-replace">
          <xsl:with-param name="text" select="substring-after($text, '?')"/>
        </xsl:call-template>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>
  
  <xsl:template match="@* | node()[not(self::text())]">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>
  
</xsl:stylesheet>

The second template is a modified version of the identity template, taken 
from the XSLT spec.  You can replace it with your normal processing if you 
wish.  I tested the template with the latest Xalan from their CVS, but it 
should work with just about any processor since it is 100% standard.
