[summary] reading xml from pipeline into a flow script
Jonathan's suggestion worked, so I thought I'd summarize the solution
back to the list as a demo javascript flow script.
function demo() {
print getXML(http://localhost:8080/cocoon/mypipeline.xml;);
}
function getXML(urlStr) {
//
// return output of a pipeline as an xml string (and/or dom)
// [NB. watch out for my app-specific parse settings below!]
//
var factory =
Packages.javax.xml.parsers.DocumentBuilderFactory.newInstance();
factory.setValidating(false);
// Prevent expansion of entity references
factory.setExpandEntityReferences(false);
// Configure it to ignore comments
factory.setIgnoringComments(true);
var document;
var isvalid = true;
try {
document = factory.newDocumentBuilder().parse(urlStr);
} catch (e) {
isvalid = false;
print(xml parse error: + e + \n);
}
var xmlStr;
if (isvalid) {
// Convert document to string
var format = new Packages.org.apache.xml.serialize.OutputFormat(document);
var strOut = new Packages.java.io.StringWriter();
var XMLSerial = new
Packages.org.apache.xml.serialize.XMLSerializer(strOut,format);
XMLSerial.serialize(document.getDocumentElement());
xmlStr = strOut.toString();
}
return xmlStr;
}

...
document.getDocumentElement();
// it is now a dom
}

Subject: reading xml from pipeline into a flow script
From within a flow script, I would like to read (or pass in) xml
generated by a series of pipeline xslt transformations.
Please could someone give me a pointer on how to do this?
Cheers

Re: reading xml from pipeline into a flow script
you can use this snippet:
function getString(src) {
try {
var is = cocoon.environment.resolveURI(src).getInputStream();
return
Packages.org.apache.cocoon.components.language.markup.xsp.XSPUtil.getContent
s(is);
}
catch(ex) {
print(ex: + ex);
}
return null;
}

RE: reading xml from pipeline into a flow script
This will work but not with the upcoming Flow Object Model. You won't
have access to the environment any more. If you are interested in the
FOM you find a reference here:
http://wiki.cocoondev.org/Wiki.jsp?page=FOM (be aware that this is a
working document and may change!!!)
So currently the easiest way is
{
...
var uri = cocoon://blablabla;
var resolver = cocoon.componentManager.lookup(
Packages.org.apache.cocoon.environment.SourceResolver.ROLE );
var srce = resolver.resolveURI( uri );
cocoon.componentManager.release( resolver );
var dom =
Packages.org.apache.cocoon.components.source.SourceUtil.toDOM( srce );
...
}
which will probably change with FOM to
{
...
var uri = cocoon://blablabla;
var resolver = cocoon.getComponent(
Packages.org.apache.cocoon.environment.SourceResolver.ROLE );
var srce = resolver.resolveURI( uri );
// release of the component (not defined yet
var dom =
Packages.org.apache.cocoon.components.source.SourceUtil.toDOM( srce );
...
}
Hope this helps!

Re: reading xml from pipeline into a flow script
Thanks. I was glad of any solution at midnight on saturday, but I'll
watch to see how the fom evolves as you advise. Thanks.
