I am working on a Schema and DTD for one of our data formats. I
need to include an "if/else" type statement for one of my elements. The
data can be stored directly in the XML file as CDATA or it can be stored in an
external entity, an HDF5 file.
Here is the element I am working on:
<!--Lowest level element, describes the
data that is present in the XDMF dataset-->
<!ELEMENT DataStructure (How do I
get to my data?, XML(internal) or ENTITY(External)>
Name CDATA #IMPLIED
Rank CDATA #IMPLIED
Dimensions CDATA #REQUIRED
Precision (4 | 8) "4"
Format (XML | HDF | Xml | Hdf) "XML"
DataType (CHAR | FLOAT | INT | COMPOUND | Char | Float | Int |
Again I'm new to XML and am not sure how to do this, so please forgive
me if I ask the same type of question a couple of times.
Thanks again for any help,
