[xml-dev] 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>
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.
