Well, I'm trying to build an xslt that uses data from a query (DB) and from an XML file as source material. I need to (and have been trying to) get the thing to work to no avail yet.

I'm testing for equality between a value from the database and the matching value from the xml. What I'm seeing is that the data from the database just isn't there at the time I test the transform.

for example:
<a:shortdescription>
<xsl:value-of select="document('xquery:///jdbc:xquery:sqlserver://localhost:1433;schema=dbo;table=Channels;user=sa;password=173A6451196704;xmlforest=true;DatabaseName=xmradio;urltype=.xml')/s:sequence/Channels/ChannelName"/>
</a:shortdescription>

returns nothing when I do the transform, but when I just examine the data 'raw' (so to speak) its there.

I've tested the DBXML data alone and its 'there'.

Not sure where I've gone wrong; although my mother can tell me endlessly...but that's another story.

Thoughts?

Hi Byron,

What do you mean by "raw"?

What do you see if you simply double click on a table in Stylus Studio File Explorer?

Also you may want to try XQuery to access relation data.
Here a useful video tutorial

Hope this helps

Hi Ivan,

Well,by raw I mean that when I double click on a table I see all the data in XML.

I'll have a look at the tutorial.

Hi Ivan,

I love this tool. I swear in the name of Wotan himself. I LOVE this tool.

Now that it looks right and all, what's the best way to deploy this to a coldfusion server?

So, it all seems to have worked. I have one question about deploying this to a web server and being able to pass in the path and name of the XML file to process.

where $Channels/ChannelNumber = doc("file:///c:/Inetpub/wwwroot/xmradio/www/xml/onXM_channels/44.xml")/channel/@number

In this case I need to be able to pass in "file:///c:/Inetpub/wwwroot/xmradio/www/xml/onXM_channels/44.xml" or more correctly just the XML document name as a variable to the java code/class that gets generated.

Byron,

You will need to declare an external variable

declare variable $inputdoc as document-node(element(*,xs:untyped)) external;

You will then replace doc(".../44.xml") with $inputdoc.

Stylus Studio bundles a servlet example (examples\XQueryWebService) that shows how to deploy xquery queries as web service.

You just need to deploy the XQueryWebService directory and copy the <stylus-folder>\bin\lib\datadirect\.* to WEB-INF\lib directory

Once the the servlet is up an running you can copy your xquery files into the servlet folder.

To get the WSDL you simply open
http://myserver/XQ
