Subject: XSTL stylesheet workarounds for exceptions

Hi All,

 

I am at a stage of fine-tuning an existing stylesheet that has been worked on recently and would like include some workarounds to accommodate exceptional data in the following 2 areas:

 

( i ) Get the content of sub-elements <a> as follows:

<p>

  <strong>Hobbies:</strong>

  <a shape="rect" href="http://www.hobbies.com/fishing title="Shark Hunting">fishing</a>

  <a shape="rect" href="http://www.hobbies.com/hunting title="Animal">rabbit</a>

(Out-door adventures)

</p>

 

Intended output

<hobbies> fishing<hobbies>

<hobbies> rabbit<hobbies>

 

In this case, it is both fishing, rabbit that I am after. However, I still couldn’t get it working despite having tried numerous of the following stylesheet approaches:

 

<xsl:template match="/">

  <employee>

    <xsl:apply-templates select="//ns:p"/>

  </employee>

</xsl:template>

 

( A ) <xsl:template match="ns:p[ns:strong='Hobbies:']">

         <xsl:copy-of             

           <hobbies>select="ns:a"/></hobbies>

       </xsl:template>

               or

( B ) <xsl:template match="ns:p[ns:strong='Hobbies:']">

         <xsl:for-each select="ns:a/text()[normalize-space() != '']">

           <hobbies><xsl:value-of select="normalize-space()"/></hobbies>

         </xsl:for-each>

       </xsl:template>

               or

( C ) <xsl:template match="ns:p[ns:strong='Hobbies:']">

         <xsl:for-each select=".//ns:a/text()[normalize-space() != '']">

           <hobbies><xsl:value-of select="normalize-space()"/></hobbies>

         </xsl:for-each>

       </xsl:template>

              or

( D ) <xsl:template match="ns:p[ns:strong='Hobbies:']">

         <xsl:for-each select="ns:p/ns:a/text()[normalize-space() != '']">

           <hobbies><xsl:value-of select="normalize-space()"/></hobbies>

         </xsl:for-each>

       </xsl:template>

               or

( E ) <xsl:template match="ns:p[ns:strong='Hobbies:']">

         <xsl:for-each select="../ns:a//text()[normalize-space() != '']">

           <hobbies><xsl:value-of select="normalize-space()"/></hobbies>

         </xsl:for-each>

       </xsl:template>

               or

( F ) <xsl:template match="ns:p[ns:strong='Hobbies:']">

         <xsl:for-each select="ns:a">

          <xsl:for-each select="text()[normalize-space() != '']">"

            <hobbies><xsl:value-of select="normalize-space()"/></hobbies>

          </xsl:for-each>

        </xsl:for-each>

     </xsl:template>

               or

( G ) <xsl:template match="ns:p[ns:strong='Hobbies:']">

          <xsl:for-each select=".//ns:a">

            <xsl:for-each select="text()[normalize-space() != '']">"

              <hobbies><xsl:value-of select="normalize-space()"/></hobbies>

            </xsl:for-each>

          </xsl:for-each>

        </xsl:template>

 

( ii ) I also like to add a default generic value for any missing element. Say if there are no

<p><strong>Hobbies:</strong></p> element in such document, yet I still would like to generate a

null element such as <hobbies>Unknown</hobbies>. The intended stylesheet should look

like the following but again couldn’t get it working still:

 

<xsl:template match="/">

  <employee>

    <xsl:apply-templates select="//ns:p"/>

  </employee>

</xsl:template>

 

<xsl: choose>

  <xsl: when test="ns:p[ns:strong='Hobbies:']">

    <xsl:template match="ns:p[ns:strong='Hobbies:']">

      <xsl:for-each select="text()[normalize-space() != '']">

        <hobbies><xsl:value-of select="normalize-space()"/></hobbies>

      </xsl:for-each>

    </xsl:template>

  </xsl:when>

<xsl:otherwise>

  <hobbies>Unknown</hobbies>

</xsl:otherwise>

</xsl: choose>

 

I have run out of ideas and would be very much appreciated if anyone could give me some suggestion on how to tackle this task.

Jack
