Hi,
I had this problem few days ago. I simply wrote my own tiny DTD with entities and structure declaration.
You can use internal DTD subset, like this: <?xml version="1.0" encoding="iso-8859-1"?> <!DOCTYPE xmlroot [ <!ENTITY myent "expand my entity to something more useful" > <!ENTITY another "another entity ..." > ]>
<document> your normal xml document, with &myent; and yet &another; entity... </document>

I'm not sure if I understand fully what you're trying to do? Could you give an example of an input and output document and maybe some code?
Sure, example document:
<document> <title>This is my test document</title> <content>This is some content with an entity here: &myent;</content> </document>
Then substitute the entities by looking up their replacements and running it through XSLT to get:
<html> <head><title>This is my test document</title></head> <body> This is some content with an entity here: myent <body> </html>
In this instance &myent; is replaced with the closest plain text match so the web browser will display it properly. This is done according to a Map:
myentities.add("&myent;", "myent"); myentities.add("π", "PI");
Right now I have a class implementing the Visitor pattern:
public void visit(Entity entity) {
System.out.println("Entity: " + myentities.get(entity.getName()));
}
The problem is that I have no where to put the entity once I lookup it's substitution, the only thing I could do would be to create a new Node with the the Visitor, add the substituted entities in as text nodes, pass the other nodes straight through. Then I would run this through XSLT, which seems expensive since it's traversing the Node twice, once to substitute, then again to do the transformation (plus keeping a duplicate Node with the substituted entities in it).
Thanks, Paul
