(I am not a Java person so I don't know the syntax for doing the following in Java. I presume it is possible. I think the approach might be useful though so here goes) The idea is to 1) have a textual representation of an XML document as a Python program 2) be able to re-create textual representations of XML document structures as Python programs The following is a Python representation of a simple XML doc:- from XMLStructures import * x = XMLTree ( XMLElement("FOO",(("ATTR1","VALUE1"),("ATTR2","VALUE2")), ( XMLElement("BAR",(),()) ) ) ) The nice thing about this is that it is both data file and parser rolled into one. A simple "import" statement recreates the in-memory representation of this data structure. Having created/manipulated an XMLTree the textual representation can be created with a single print statement:- x = XMLTree ( XMLElement("FOO",(("ATTR1","VALUE1"),("ATTR2","VALUE2")), ( XMLElement("BAR",(),()) ) ) ) # Change x here # ... print x XMLTree (XMLElement ("FOO",(('ATTR1', 'VALUE1'), ('ATTR2', 'VALUE2')),XMLElement ("BAR",(),()))) 1) Such structures give an immediate API in the form of Lispy list processing stuff. 2) Such structures allow parsers to be compared / checked for correct interpretation of XML. 3) Such structures give developers something to aim at when developing XML markup aware tools. Just in case anyone is interested, here is the Python code for the classes :- class XMLTree: def __init__ (self,r): self.root = r def __repr__ (self): return "XMLTree (%s)" % (self.root,) class XMLElement: def __init__(self,gi,attlist,children): self.GI = gi self.XMLAttlist = attlist self.Children = children def __repr__(self): return "XMLElement (\"%s\",%s,%s)" % (self.GI,self.XMLAttlist,self.Children) class XMLPcdata: def __init__(self,dat): self.data = dat def __repr__(self): return self.data Sean Mc Grath sean@d...
