Replace functionality using XSLT

Introduction:

In my previous article I have explained about Read cookies value using C#.net Asp.Net. In this article I am going to explain the replace functionality using xslt.

Explanation:

I need to replace space with – symbol in my input. So I wrote a below template to do this operation.

<xsl:template name="string-replace-all">

  <xsl:param name="text" />

  <xsl:param name="replace" />

  <xsl:param name="by" />

  <xsl:choose>

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

      <xsl:value-of select="substring-before($text,$replace)" />

      <xsl:value-of select="$by" />

      <xsl:call-template name="string-replace-all">

        <xsl:with-param name="text"

        select="substring-after($text,$replace)" />

        <xsl:with-param name="replace" select="$replace" />

        <xsl:with-param name="by" select="$by" />

      </xsl:call-template>

    </xsl:when>

    <xsl:otherwise>

      <xsl:value-of select="$text" />

    </xsl:otherwise>

  </xsl:choose>

</xsl:template>

Now I have called the function like below mentioned.

<xsl:variable name="myVar">

  <xsl:call-template name="string-replace">

    <xsl:with-param name="text" select="'This is a sample text with space'" />

    <xsl:with-param name="replace" select="' '" />

    <xsl:with-param name="by" select="'-'" />

  </xsl:call-template>

</xsl:variable>

Now if we print the value of  myVar then it will be This-is-a-sample-text-with-space

But if you like to replace only one character then you can use translate the method instead of the above method. Below is the sample code.

<xsl:value-of select="translate(Productservicename,' ','')"/>

Please note that method translate will replace only one character.
