[jdom-interest] Entity Ref

Thank you very much for your timely reply.

Here is my procedure:
1. Client uploads csv generated from legacy system.
2. I convert the file to xml and then use jdom to group fields with like
terms, sum one of the columns, ect.

My problem is that one for the columns needs to be expanded so that it will
display properly when converted with XSL to HTML.

legacy generated csv line:
3.500,9.30,"P-110","8-RD EUE","MAHA","HOUSTON","IN STOCK",660.00

jdom generated line:
<item id="0" size="3.500" weight="9.30" grade="P-110" endFin="8-RD EUE"
mill="MAHA" location="HOUSTON" status="IN STOCK" footage="660.0"
price="1.00" />

The solution that I would like to implement is as follows:
If I add a dtd as follows and modify the mill attribute to be an entity,
<!ENTITY MAHA "New API Seamless Maharashtra">

The xml parser expands this to:
<item id="0" size="3.500" weight="9.30" grade="P-110" endFin="8-RD EUE"
mill="New API Seamless Maharashtra" location="HOUSTON" status="IN STOCK"
footage="660.0" price="1.00" />

This is why I would like my jdom generated file to read as:
<item id="0" size="3.500" weight="9.30" grade="P-110" endFin="8-RD EUE"
mill="&MAHA;" location="HOUSTON" status="IN STOCK" footage="660.0"
price="1.00" />

I apologize if I am missing something.  It is just that it works fine if I
manually add the entities to an xml file and read from the data from there.
I just wish I could do this programmatically using JDOM.  I would appreciate
any suggestions.

Thank you in advance,

Not really. You're confusing the lexical and syntactic layers of XML.
XSLT won't act any differently whether the text is output with an
entity reference or something else. I still don't quite follow what
you're doing, but it sounds like you need to adjust your design a
little so that you neither know or care whether  it's the entity
reference or the actual text when processing.
