Hi guys, Last days, i have been working on a new prototype about a certain kind of XML pipelines support in Sling [1]. The prototype is making these main assumptions:
1. A XML pipeline is expressed as a W3C XProc [2] file with "xpl" extension. For instance: <p:pipeline xmlns:p="http://www.w3.org/ns/xproc";> <p:xslt> <p:input port="stylesheet"> <p:document href="http://localhost:8888/xpl-sample/xsl/test-content.xslt"/> </p:input> </p:xslt> </p:pipeline> 2. The pipeline (xpl file) is interpreted by a scripting engine named "XProc" or "XML pipeline processor". 3. The XProc script engine relies on Cocoon 3 Pipeline in order to setup and execute the pipeline. 4. A Cocoon generator named SlingGenerator is responsible for preparing the input data. 5. A Cocoon transformer named SlingXsltTransformer will be responsible for resolving XSLT templates. Now, my main problem is the point 4. Because of the generator needs an InputStream with XML data, my first approach was: /apps/sling/xpl/sample/html.xpl /xpl-sample/pipelines/test_pipeline +-- sling:resourceType: "sling/xpl/sample" +-- sling:datasource: "/xpl-sample/test.xml" /xpl-sample/test.xml private InputStream genXml() throws Exception { Resource resource = request.getResource(); Map props = resource.adaptTo(Map.class); String absPathGen = props.get("sling:datasource").toString(); Resource genResource = request.getResourceResolver().resolve(absPathGen); return genResource.adaptTo(InputStream.class); } This is ok if my data source is a XML file but, what happens if we have another reource type?. For instance, I´d like been able to generate XML data source as a result of executing a script. I tried this, in a similar way that "SlingRequestDispatcher include" works, but I didn´t succeed. Any ideas?. Thanks in advance, BR, Juanjo. [1] https://svn.apache.org/repos/asf/incubator/sling/whiteboard/jvazquez/org.apache.sling.scripting.xproc [2] http://www.w3.org/TR/xproc/
