XSL Attribute Test

Q) How to check whether the value of an attribute is not null or if the lenght of characters in the value of an attribute is greater than 0?

Solution applied -->
s0SelectedSite is an attribute of a class or a column of a table.

Expand|Select|Wrap|Line Numbers
  1. <xsl:if test="string-length(@s0SelectedSite) &gt; '0'">
  2. <tr>
  3.   <td width="50%" bgcolor="#C0C0C0"><font size="2"><b>Selected Site:</b></font></td>
  4.   <td><font size="2">*<xsl:apply-templates select="DBE:Attribute   [@name='s0SelectedSite']"/></font></td>
  5. </tr> 
  6. </xsl:if>
In the above, the value of s0SelectedSite exists but still the lines are not getting printed.

For eg. It should display the following:-

Selected Site: Singapore
Please let me know if something is wrong.

I tried this way now --> It worked for me :

Expand|Select|Wrap|Line Numbers
  1. <xsl:choose>
  2.   <xsl:when test="string-length(DBE:Attribute[@name='s0SelectedSite']/node()) &gt; 0"> 
  3.     <table>
  4. ...<tr> 
  5.   <td width="50%" bgcolor="#C0C0C0"><font size="2"><b>Selected Site:</b></font></td> 
  6.   <td><font size="2">*<xsl:apply-templates select="DBE:Attribute   [@name='s0SelectedSite']"/></font></td> 
  7. </tr>
  8.     </table>
  9.   </xsl:when>
  10.   <xsl:otherwise>
  11.     <table>
  12. ...<tr> 
  13.   <td width="50%" bgcolor="#C0C0C0"><font size="2"><b>Selected Site:</b></font></td> 
  14.   <td><font size="2">*<xsl:apply-templates select="DBE:Attribute   [@name='s0SelectedSite']"/></font></td> 
  15. </tr>
  16.     </table>
  17.   </xsl:otherwise>
  18. </xsl:choose>

@prao2005
that is correct behaviour. if you want to skip empty values, you have to test for them before.
