RE: Converting embedded URLs int hot links via XSL

Here's an approach you could use.  The "choose's" and "substring-before's"
and "substring-after's" get kind of shaggy.  And choice of substring
conditions make some pretty lazy assumptions about the expected form of the
url's, but you get the idea:

<xsl:template match="node()|@*">
 <xsl:copy>
  <xsl:apply-templates select="@*|node()"/>
 </xsl:copy>
</xsl:template>

<xsl:template match="text()" priority="2">
 <xsl:choose>
  <xsl:when test="contains(.,'http')">
   <xsl:variable name="after.com" select="substring-after(.,'.com')" />
   <xsl:value-of select="substring-before(.,'http')" />
    <a>
     <xsl:attribute name="href">
      <xsl:value-of
select="concat('http',substring-after(substring-before(.,'.com'),'http'),'.c
om')" />
     </xsl:attribute>
     <xsl:value-of
select="concat('http',substring-after(substring-before(.,'.com'),'http'),'.c
om')" />
    </a> 
    <xsl:call-template name="lazy-recurs">
     <xsl:with-param name="after-.com">
      <xsl:value-of select="$after.com" />
     </xsl:with-param>
    </xsl:call-template>
  </xsl:when>
  <xsl:otherwise>
   <xsl:value-of select="." />
  </xsl:otherwise>
 </xsl:choose>
</xsl:template>

<xsl:template name="lazy-recurs">
 <xsl:param name="after-.com" />
  <xsl:choose>
   <xsl:when test="contains($after-.com,'http')">
    <xsl:variable name="after.com"
select="substring-after($after-.com,'.com')" />
      <xsl:value-of select="substring-before($after-.com,'http')" />
       <a>
        <xsl:attribute name="href">
         <xsl:value-of
select="concat('http',substring-after(substring-before($after-.com,'.com'),'
http'),'.com')" />
        </xsl:attribute>
        <xsl:value-of
select="concat('http',substring-after(substring-before($after-.com,'.com'),'
http'),'.com')" />
       </a>
     <xsl:call-template name="lazy-recurs">
      <xsl:with-param name="after-.com">
       <xsl:value-of select="$after.com" />
      </xsl:with-param>
     </xsl:call-template>
   </xsl:when>
   <xsl:otherwise>
    <xsl:value-of select="$after-.com" />
   </xsl:otherwise>
  </xsl:choose>
</xsl:template>

Subject:  Converting embedded URLs int hot links via XSL


Here is the sample xml

<strings>
<str>Test url string: 'http://www.yahoo.com' and one
more url "https://www.yahoo.com"</str>
</strings>

So, is there a way to extract the urls above from str
and then convert them into hotlinks. The desired html
is something like
Test url string: <a href="http://www.yahoo.com"
target="_blank">'http://www.yahoo.com'</a> and one
more url <a href="https://www.yahoo.com"
target="_blank">"https://www.yahoo.com"</a>

I've tried recursion but it doesn't work. Any ideas???

Thanks,
Abbas
