Re: JPath Problem

[Jeroen Reijn]

Hi,

when looking at your for-each I notice that your xpath isn't correct. It 
says 'directory/metada/raw-images/ ' instead of 'metadata'
Could this be your problem then?

Everything else looks fine.

Greetz,

Hi there,

I have a problem with a JPath expression that schould iterate over 
some elements of DOM tree. It should be very easy but for some reason 
it is not working. The XML data looks like the following:

<site>
  <directory title="...">
     <file>...</file>
     <file>...</file>
     <metadata>
        <raw-images>
           <image file="...">
              <raw>
                  <tag dir="Exif" name="Make">SONY</tag>
                  <tag dir="Exif" name="Date/Time">13.12.2003</tag>
                  ...
               </raw>
           </image>
           <image file="...">
              <raw>
                  <tag dir="Exif" name="Make">CANON</tag>
                  <tag dir="Exif" name="Date/Time">15.11.2001</tag>
                  ...
               </raw>
           </image>
        </raw-images>
     </metadaten>
  </directory>
What i want to do is just to save the "make" of  the images to a 
variable and then write it to my database with esql.

My jpath expression looks like the following:

<jpath:for-each select="site/directory/metada/raw-images/image">
               <xsp:logic>make=(String)<jpath:value-of 
select="./raw/[EMAIL PROTECTED]'Make']"/>;</xsp:logic>
</jpath>

But i always get an 'No value for xpath: ./raw/[EMAIL PROTECTED]'Make']'

What is so strange about this is that the path should be correct 
because if i am using the <jpath:value-of select> outside the for-each 
loop with an absolute url:

<xsp:logic>make=(String)<jpath:value-of 
select="site/directory/metadata/raw-images/image/raw/[EMAIL PROTECTED]'Make']"/>;</xsp:logic> 

i can access the "Make".

Maybe it is just a stupid mistake but i just don't know what's wrong. 
I am thankfull for any hints!

regards,
Garvin
