Hi
Laura,Mr Kay,Vasu.
and of course everyone on the list.

Me again.


Please see the following snippet:


<xsl:for-each select="attr[@name='addrdesc1' or @name='AddrDesc1']">
    <td>&#160; <input type="text">
     <xsl:attribute name="name">txtAddressDesc</xsl:attribute>
     <xsl:attribute name="value"><xsl:value-of select
="value"></xsl:value-of></xsl:attribute>
     </input>
         </td>
</xsl:for-each>



Now consider for instance the above for-each does'nt return a value at all.
I.e there is'nt an attribute called addrdesc1 in the xml schema response
So obviously it does't enter the for-each and does NOT display the text
box.

but i still want to display an empty text box to the user
in the XSL , How do i do this???

May be i can get a count, or something


Regards,
Suman
