Hi Josep, I'm not an XML expert, but my understanding is that things inside a <configure> tag is #PCDATA, which should not be interpreted against the DTD? http://ptolemy.eecs.berkeley.edu/xml/dtd/MoML_1.dtd has: <!ELEMENT configure (#PCDATA)>
For information about the configure tag, see page 220 of Volume 1 of the Ptolemy II Design Doc at http://www.eecs.berkeley.edu/Pubs/TechRpts/2008/EECS-2008-28.html: --start A second, much more flexible mechanism is provided for parameterizing entities. A configure element can be used to specify a relative or absolute URL pointing to a file that configures the entity, or it can be used to include the configuration information in line. That information need not be MoML information. It need not even be XML, and can even be binary encoded data (although binary data cannot be in line; it must be in an external file). For example, <entity name="sink" class="ptolemy.actor.lib.SequencePlotter"> <configure source="url"/> </entity> Here, url can give the name of a file containing data, or a URL for a remote file. (For the Sequence- Plotter actor, that external data will have PlotML syntax; PlotML is another XML schema for configuring plotters.) Configure information can also be given in the body of the MoML file as follows: <entity name="sink" class="ptolemy.actor.lib.SequencePlotter"> <configure> configure information </configure> </entity> With the above syntax, the configure information must be textual data. It can contain XML markup with only one restriction: if the tag ?</configure>? appears in the textual data, then it must be preceeded by a matching ?<configure>?. That is, any configure elements in the markup must have balanced start and end tags. You can give both a source attribute and in-line configuration information, as in the following: <entity name="sink" class="ptolemy.actor.lib.SequencePlotter"> <configure source="url"> configure information </configure> </entity> In this case, the file data will be passed to the application first, followed by the in-line configuration data. In Ptolemy II, the configure element is supported by any class that implements the Configurable interface. That interface defines a configure() method that accepts an input stream. Both external file data and in-line data are provided to the class as a character stream by calling this method. There is a subtle limitation with using markup within the configure element. If any of the elements within the configure element match MoML elements, then the MoML DTD will be applied to assign default values, if any, to their attributes. Thus, this mechanism works best if the markup within the configure element is not using an XML schema that happens to have element names that match those in MoML. Alternatively, if it does use MoML element names, then those elements are used with their MoML meaning. This limitation can be fixed using XML namespaces, something we will eventually implement. --end-- My guess is that JDOM needs to be adjusted so that it does not try to interpret the #PCDATA? A quick google search did not bring up anything. You could also try running JDOM on a model that has a Ptolemy PlotML xml in a configure tag. For example, http://ptolemy.eecs.berkeley.edu/ptolemyII/ptIIlatest/ptII/ptolemy/domains/sdf/demo/Butterfly/Butterfly.xml has <entity name="XY Plotter" class="ptolemy.actor.lib.gui.XYPlotter"> <property name="fillOnWrapup" class="ptolemy.data.expr.Parameter" value="true"> </property> <property name="_windowProperties" class="ptolemy.actor.gui.WindowPropertiesAttribute" value="{bounds={258, 206, 500, 344}, maximized=false}"> </property> <property name="_plotSize" class="ptolemy.actor.gui.SizeAttribute" value="[500, 300]"> </property> <property name="startingDataset" class="ptolemy.data.expr.Parameter" value="0"> </property> <property name="_location" class="ptolemy.kernel.util.Location" value="[488.5, 265.5]"> </property> <configure> <?plotml <!DOCTYPE plot PUBLIC "-//UC Berkeley//DTD PlotML 1//EN" "http://ptolemy.eecs.berkeley.edu/xml/dtd/PlotML_1.dtd";> <plot> <title></title> <xRange min="-2.4845557281711192" max="3.9293144658408363"/> <yRange min="-3.6505369457601655" max="3.6505369457601127"/> <noGrid/> </plot>?> </configure> </entity> It could be that it would be better if the dtd was declared in <svg>...</svg> example, but I'm no expert in this area. It could be that by definition, a validating parser tries to validate #PCDATA. _Christopher On 1/12/10 11:25 AM, Chad Berkley wrote: > Hi Josep, > > I'll let Christopher Brooks explain why it's not in the DTD (the ptolemy > project controls the MoML DTD).
