Sorry about that.
Here is what I"m doing
<xsl:template name="extract">
<xsl:param name="strEmbUrl"/>
<xsl:param name="delim1"/>
<xsl:param name="delim2"/>
<xsl:choose>
<xsl:when test="contains($strEmbUrl, $delim1)">
<xsl:variable name="strB4"
select="substring-before($strEmbUrl, $delim1)"/>
<xsl:variable name="strAfter"
select="substring-after($strEmbUrl, $delim1)"/>
<xsl:variable name="lastCh"
select="substring($strAfter,
string-length($strAfter))"/>
<xsl:choose>
<xsl:when test="$lastCh = $delim2">
<xsl:choose>
<xsl:when test="contains($strAfter, $delim2)">
<xsl:variable name="emURL"
select="substring-before($strAfter, $delim2)"/>
<!-- #1 Solution -->
<xsl:value-of select="$strB4"/><a
href="<xsl:value-of select="concat($delim1,$emURL)"/>"
target="_blank"><xsl:value-of
select="concat($delim1, $emURL)"/></a>>
<!-- #2 Solution -->
<xsl:value-of select="$strB4"/><xsl:variable
name="link" select="concat($delim1,$emURL)"/>
<a target="_blank" href="{$link}">
<xsl:value-of select="$link"/></a>
<!-- #3 Solution -->
<xsl:value-of select="$strB4"/><xsl:element
name="A"><xsl:attribute name="href"><xsl:value-of
select="concat($delim1,$emURL)"/></xsl:attribute><xsl:attribute
name="target"><xsl:value-of
select="'_blank'"/></xsl:attribute><xsl:value-of
select="concat($delim1, $emURL)"/></xsl:element>
<!-- end problematic code -->
<xsl:call-template name="extract">
<xsl:with-param name="delim1" select="$delim1"/>
<xsl:with-param name="delim2" select="$delim2"/>
<xsl:with-param name="strEmbUrl"><xsl:value-of
select="substring-after($strEmbUrl,
$emURL)"/></xsl:with-param>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$strEmbUrl"/>
</xsl:otherwise>
</xsl:choose>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$strEmbUrl"/>
</xsl:otherwise></xsl:choose></xsl:when>
<xsl:otherwise><xsl:value-of select="$strEmbUrl"/>
</xsl:otherwise></xsl:choose></xsl:template>
<xsl:template name="extractEmbeddedURLs">
<xsl:param name="str"/>
<xsl:call-template name="extract">
<xsl:with-param name="delim1" select="'http://'"/>
<xsl:with-param name="delim2">'</xsl:with-param>
<xsl:with-param name="strEmbUrl">
<xsl:call-template name="extract">
<xsl:with-param name="delim1" select="'http://'"/>
<xsl:with-param name="delim2">"</xsl:with-param>
<xsl:with-param name="strEmbUrl" select="$str"/>
</xsl:call-template>
</xsl:with-param>
</xsl:call-template>
</xsl:template>
Solution 1,2,3 are the problem area. I tried these 3
but first iteration works fine but when it goes into
the subsequent iteration string containing html is
lost somewhere. i.e. If I call extract only once then
it works fine and browser is able to render the html
but recursion seems to have some problem.

There is a bug in your code. How do you expect
anyone to tell you where
you've gone wrong if you don't show us your code?
It's necessary to show your code for two reasons:
(a) so people can tell you where your mistakes are
(b) so people can judge your level of experience and
knowledge, and phrase
their replies accordingly.
