Replace String

[Hvid Hat]

Hi

I want to highlight (make it bold) a word in some text I'm getting in XML
format. My plan was to replace the word with a bold (or span) tag with the
word within the tag. I've found the code below and it works fine as long
as I'm not adding tags around the to parameter. Can anyone explain to me
why it doesn't work with tags? And it needs to be XSLT 1.0.

This works: X<xsl:value-of select="'little steak'"/>X
This doesn't work: <b><xsl:value-of select="'little steak'"/></b>

And the code:

<?xml version="1.0"?>
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform" version="1.0">

<!-- reusable replace-string function -->
<xsl:template name="replace-string">
<xsl:param name="text"/>
<xsl:param name="from"/>
<xsl:param name="to"/>

<xsl:choose>
<xsl:when test="contains( $text, $from)">

<xsl:variable name="before" select="substri ng-before($text, $from)"/>
<xsl:variable name="after" select="substri ng-after($text, $from)"/>
<xsl:variable name="prefix" select="concat( $before, $to)"/>

<xsl:value-of select="$before "/>
<xsl:value-of select="$to"/>
<xsl:call-template name="replace-string">
<xsl:with-param name="text" select="$after"/>
<xsl:with-param name="from" select="$from"/>
<xsl:with-param name="to" select="$to"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwis e>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

<!-- test the function -->
<xsl:template match="/">
<xsl:call-template name="replace-string">
<xsl:with-param name="text"
select="'Mary had a little lamb, little lamb, little lamb.'"/>
<xsl:with-param name="from" select="'little lamb'"/>
<xsl:with-param name="to">
<!-- X<xsl:value-of select="'little steak'"/>X -->
<b><xsl:value-of select="'little steak'"/></b>
</xsl:with-param>
</xsl:call-template>
</xsl:template>
</xsl:stylesheet>

You are using <xsl:value-of select="$to"/>, that outputs a text node
with the string value, it does not create elements.

If you use xsl:copy-of as in

<xsl:template name="replace-string">
<xsl:param name="text"/>
<xsl:param name="from"/>
<xsl:param name="to"/>

<xsl:choose>
<xsl:when test="contains( $text, $from)">

<xsl:variable name="before" select="substri ng-before($text, $from)"/>
<xsl:variable name="after" select="substri ng-after($text, $from)"/>
<xsl:variable name="prefix" select="concat( $before, $to)"/>

<xsl:value-of select="$before "/>
<xsl:copy-of select="$to"/>
<xsl:call-template name="replace-string">
<xsl:with-param name="text" select="$after"/>
<xsl:with-param name="from" select="$from"/>
<xsl:with-param name="to" select="$to"/>
</xsl:call-template>
</xsl:when <xsl:otherwis e>
<xsl:value-of select="$text"/ </xsl:otherwise>
</xsl:choose </xsl:template>

then I think you get what you want.

Re: Replace String

Thanks. Both your suggestions worked. Now I'm working on making the search
case-insensitive. Is there an easy way? Or can you guide me in the right
direction?

Re: Replace String

Hello Hvid,

Ok. Now I can replace the search string no matter what case it's in. Unfortunately
I haven't found a way to keep the original case of the search sting in the
text. Anyone? Here's my code:

<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:variable name="lcletters ">abcdefghijklm nopqrstuvwxyz</xsl:variable>
<xsl:variable name="ucletters ">ABCDEFGHIJKLM NOPQRSTUVWXYZ</xsl:variable>

<xsl:template name="replace-string">
<xsl:param name="text"/>
<xsl:param name="from"/>
<xsl:param name="to"/>
<xsl:choose>
<xsl:when test="contains( translate($text , $ucletters, $lcletters), translate($from ,
$ucletters, $lcletters))">
<xsl:variable name="before" select="substri ng-before(translat e($text,
$ucletters, $lcletters), translate($from , $ucletters, $lcletters))"/>
<xsl:variable name="after" select="substri ng-after(translate ($text, $ucletters,
$lcletters), translate($from , $ucletters, $lcletters))"/>
<xsl:variable name="prefix" select="concat( $before, $to)"/>
<xsl:value-of select="$before "/>
<xsl:copy-of select="$to"/>
<xsl:call-template name="replace-string">
<xsl:with-param name="text" select="$after"/>
<xsl:with-param name="from" select="$from"/>
<xsl:with-param name="to" select="$to"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwis e>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="/">
<xsl:call-template name="replace-string">
<xsl:with-param name="text" select="'Mary had a little lamb, LITTLE LAMB,
x little lamb.'"/>
<xsl:with-param name="from" select="'little lamb'"/>
<xsl:with-param name="to">
<!-- X<xsl:value-of select="'little steak'"/>X -->
<b>
<xsl:value-of select="'little steak'"/>
</b>
</xsl:with-param>
</xsl:call-template>
</xsl:template>
</xsl:stylesheet>
