Help with XML and DOM Classes

[Adrian Crum]

I'm working on the entity engine model classes to include support for accessing the description
elements during run time. I've run into a problem I can't figure out.

Using the following entity definition:

<entity entity-name="Content" package-name="org.ofbiz.content.content" title="Content Entity">
   <field name="ownerContentId" type="id"><description>Used for permissions
checking</description></field>
   ...
</entity>

I have the description Element in code, but I can't seem to get the text of the description:

NodeList descriptionList = fieldElement.getElementsByTagName("description");
for (int i = 0; i < descriptionList.getLength(); i++) {
     Element element = (Element) descriptionList.item(i);
     if (element.getNodeValue() != null) {
         this.description = element.getNodeValue();
     }
}

I've tried getNodeValue() and getTextContent(), but both return null.

Any ideas?

Never mind - I discovered UtilXml.childElementValue(...)

Problem solved.

Adrian,

this is probably a bit off topic, but recently (while working on the
Business Intelligence application) I've completed some support to access
descriptions on entities and views' fields.
I don't remember the details (and I'm not even sure you are trying to do
something similar) but you may have a look at the way metadata are
retrived in the bsh script:

http://svn.apache.org/repos/asf/ofbiz/trunk/specialpurpose/bi/webapp/bi/WEB-INF/actions/reportbuilder/getStarSchemaFields.bsh

Jacopo,

Yes, that is exactly what I am working on. Did you notice that

String description = field.getDescription();

doesn't work?

It seems to be working here:

https://localhost:8443/bi/control/ReportBuilderSelectStarSchema

submit the form and the next screen will show meta data info (using the
script)

Ah. That's because you're using ModelAlias. ModelField.getDescription() doesn't work.

I should have a patch ready in a few hours.
