Re: javascript, xsl and xml

David,

thankyou for your reply - yes I should have been more specific (probably
due to my lack of knowledge as to how to crack my problem)

The xml I am trying to pass is well formed I believe, something along
the lines of:

 <vs:Table role="out"
xmlns:vs="http://www.ivoa.net/xml/VODataService/v0.4";> 
  <vs:Table>sgas_event</vs:Table> 
  <vs:Column> 
   <Name>time_start</Name> 
   <Description>Start time of the solar event.</Description> 
   <vs:DataType arraysize="*">char</vs:DataType> 
  </vs:Column> 
  <vs:Column> 
   <Name>time_peak</Name> 
   <Description>Peak time of the solar event.</Description> 
   <vs:DataType arraysize="*">char</vs:DataType> 
  </vs:Column> 
  <vs:Column> 
   <Name>time_end</Name> 
   <Description>End time of the solar event.</Description> 
   <vs:DataType arraysize="*">char</vs:DataType> 
  </vs:Column>
.................

I then have my function in the stylesheet:

<xsl:element name="img">
  <xsl:attribute    
name="src">/astrogrid-portal/AGRightFrame.gif</xsl:attribute>
   <xsl:attribute name="onclick">backToRightFrameDC('<xsl:value-of
select="@val"/>');
   </xsl:attribute>
</xsl:element>

Onclicking the image to call the function I get

Error: unterminated string literal
Source Code:
backToRightFrameDC('<vodescription><vr:Resource
xmlns:vr="http://www.ivoa.net/xml/VOResource/v0.9";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="RegistryType">

with the unterminated string literal occuring at the 1st '<'...

Any further assistance much appreciated so I can have a weekend without
this troubling me!
