Re: [xsl] Placing mark-up in between strings

[Jeff Sese <jsese@xxxxxxxxxxxx>]

I have tried this template:

<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
xmlns:xs="http://www.w3.org/2001/XMLSchema"; 
xmlns:ati="http://www.asiatype.com/xslt-functions"; 
exclude-result-prefixes="xs ati">
<xsl:output method="xml" encoding="UTF-8"/>
<xsl:template name="start">
   <xsl:variable name="input-str" as="xs:string" select="'This is 
supposed to be my input string with search1, search2, and search3. There 
is another search1.'"/>
   <xsl:variable name="search-str" as="xs:string*" 
select="('search1','search2','search3')"/>
   <xsl:variable name="replace-str" as="xs:string*" 
select="('replace1','replace2','replace3')"/>
   <p><xsl:sequence select="ati:tag($input-str, $search-str, 
$replace-str)"/></p>
</xsl:template>
<xsl:function name="ati:tag" as="node()+">
   <xsl:param name="input-str" as="xs:string"/>
   <xsl:param name="search-str" as="xs:string*"/>
   <xsl:param name="replace-str" as="xs:string*"/>
   <xsl:choose>
       <xsl:when test="exists($search-str)">
           <xsl:value-of select="substring-before($input-str, 
$search-str[1])"/>
           <replacement value="{$replace-str[1]}"><xsl:sequence 
select="$search-str[1]"/></replacement>
           <xsl:sequence select="ati:tag(substring-after($input-str, 
$search-str[1]),remove($search-str,1),remove($replace-str,1))"/>
       </xsl:when>
       <xsl:otherwise>
           <xsl:value-of select="$input-str"/>
       </xsl:otherwise>
   </xsl:choose>
</xsl:function>
</xsl:stylesheet>

And got this output:

<?xml version="1.0" encoding="UTF-8"?>
<p>This is supposed to be my input string with <replacement 
value="replace1">search1</replacement>, <replacement 
value="replace2">search2</replacement>, and <replacement 
value="replace3">search3</replacement>. There is another search1.</p>

My template will only tag the first occurrence of the search string, 
because i'm using substring-before and substring-after approach. Also, i 
want to avoid placing mark-ups to the search string that is already 
marked-up. Example i don't want this to happen.

<p>This is supposed to be my input string with <replacement 
value="replace1"><replacement 
value="replace1">search1</replacement></replacement>, <replacement 
value="replace2">search2</replacement>, and <replacement 
value="replace3">search3</replacement>. There is another <replacement 
value="replace1">search1</replacement>.</p>

That's why i don't want to loop back to the start of the string. I was 
thinking of using this, '<replacement 
value="replace1">search1</replacement>', as the replacement string and 
then just us d-o-e, but i want to avoid using d-o-e because there might 
be part of the string that i don't want to do d-output-e.

Is there any alternative solution to this?
