Hi Senthilkumaravelan,
I have difficulty in recursive replacement of escapes. Thanks for showing your sample XML and desired output so clearly. One thing confuses me, though: your sample XML contains element names that are escaped with both double square brackets, such as [[BUYERS_NAME]] and single ones, such as [WEB_ORDER_NUMBER]. I'm going to assume you just want to use single square brackets. First, I'd set up a key that holds the elements that hold the values you want to insert, such as <BUYERS_NAME>. <xsl:variable name="replacements"
select="/broadcast/ORDER_FEED/ORDER/ORDER_HEADER/*" />Then I'd write a recursive template that takes a string, looks for the first [, and outputs the string up to the first [, then the replacement value for the substring between the first [ and the next ], and finally calls itself on the substring after the ]: <xsl:template name="replace-escapes">
<xsl:param name="string" />
<xsl:choose>
<xsl:when test="contains($string, '[')">
<!-- substring before the escaped sequence -->
<xsl:value-of select="substring-before($string, '[')" /> <!-- replacement for the string between the []s -->
<xsl:variable name="ename"
select="substring-before(substring-after($string, '['), ']')" />
<xsl:value-of select="$replacements[name() = $ename]" /> <!-- recursive call on the rest of the string -->
<xsl:call-template name="replace-escapes">
<xsl:with-param name="string"
select="substring-after(substring-after($string, '['), ']')"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$string" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>I'd call this template from a template matching text nodes in the <content> of your XML. I'd use a 'copy' mode to copy all the elements in this <content> while escaping the text. The templates would look something like: <xsl:template match="broadcast">
<xsl:apply-templates select="content_vars/content/*"
mode="copy" />
</xsl:template><xsl:template match="*" mode="copy">
<xsl:copy>
<xsl:copy-of select="@*" />
<xsl:apply-templates mode="copy" />
</xsl:copy>
</xsl:template><xsl:template match="text()" mode="copy">
<xsl:call-template name="replace-escapes">
<xsl:with-param name="string" select="." />
</xsl:call-template>
</xsl:template>You could use keys instead of a global variable holding the replacement values, but I hope this gets you on the right track. Cheers, Jeni -- Jeni Tennison http://www.jenitennison.com
