Description:
XSLT has no first-class function to search-and-replace. Instead this
recipe implements it as a template.
Source: Text Source
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template name="replace-string">
<xsl:param name="text"/>
<xsl:param name="from"/>
<xsl:param name="to"/>
<xsl:choose>
<xsl:when test="contains($text, $from)">
<xsl:variable name="before" select="substring-before($text, $from)"/>
<xsl:variable name="after" select="substring-after($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:otherwise>
<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, little lamb.'"/>
<xsl:with-param name="from" select="'little lamb'"/>
<xsl:with-param name="to" select="'little steak'"/>
</xsl:call-template>
</xsl:template>
</xsl:stylesheet>
The license for this recipe is available here.
Discussion:
There are various versions of this function floating around. This one
is based upon Steve Ball's XSLTSL. You can find out more about that
package here: http://xsltsl.sourceforge.net/

There is a search and replace function in XSLT., Pontus Östlund, 2005/05/29
This is how it can be done:
<xsl:variable name="var" select="'this:is:a:sentence'"/>
<xsl:value-of select="translate($var, ':', ' ')"/>

Re: translate(), Not specified Not specified, 2005/06/20
Yes, but translate() only replaces one-character strings with one-character strings. There is no way to replace 'little lamb' with 'little steak'.

$prefix, Not specified Not specified, 2005/06/20
Thanks for a useful sample.
Question: the $prefix variable appears never to be used. What's it there for?

Hi
I tried the search and replace function but it creates a new table for my code instead of putting them in the same column from which i am picking up the data, any idea.
thanks

Replacing http://www.abc.com with <a href='http://www.abc.com '>http://www.abc.com </a>, manish goyal, 2006/04/21
I have a node called <description> some desc
</description>. The node exactly look like this:
<forum>
<description>
Some text will come over here with a link http://www.abc.com after this also there can be text and then a link https://www.xyz.com and again some text.
<description>
What I want is while XSL is transforming the the above node...it should transform in such a way that http://www.abc.com behaves like a link...so when anybody clicks on that it open a browser window. In a summary I would like to append <a href> tag to all the occurence of http:// or https://.
Please help me out.
