> I am getting a String somehow which contains %20 or space characters. > like 'This%20is%20Test' and I want to convert it to 'This is Test' General purpose substring replacement should be in the FAQ, but I couldn't find it. The closest I found was an answer by Michael Kay to a similar question, and which I just posted a modified version of yesterday for someone else. Here is yet another version. <!-- pretend this is in a template --> <xsl:variable name="myString" select="'This%20is%20Test'"/> <xsl:variable name="myNewString"> <xsl:call-template name="replaceCharsInString"> <xsl:with-param name="stringIn" select="string($myString)"/> <xsl:with-param name="charsIn" select="'%20'"/> <xsl:with-param name="charsOut" select="' '"/> </xsl:call-template> </xsl:variable> <!-- $myNewString is a result tree fragment, which should be OK. --> <!-- If you really need a string object, do this: --> <xsl:variable name="myNewRealString" select="string($myNewString)"/> <!-- here is the template that does the replacement --> <xsl:template name="replaceCharsInString"> <xsl:param name="stringIn"/> <xsl:param name="charsIn"/> <xsl:param name="charsOut"/> <xsl:choose> <xsl:when test="contains($stringIn,$charsIn)"> <xsl:value-of select="concat(substring-before($stringIn,$charsIn),$charsOut)"/> <xsl:call-template name="replaceCharsInString"> <xsl:with-param name="stringIn" select="substring-after($stringIn,$charsIn)"/> <xsl:with-param name="charsIn" select="$charsIn"/> <xsl:with-param name="charsOut" select="$charsOut"/> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$stringIn"/> </xsl:otherwise> </xsl:choose> </xsl:template> - Mike ____________________________________________________________________ Mike J.
