http://www.erights.org/elang/kernel/index.html now has a significantly
expanded, but still woefully inadequate, explanation of the constructs of
Kernel-E, and their proposed translations to XML and Java.
http://www.erights.org/elang/kernel/kernel-e-0.8.9.dtd is the proposed XML
DTD for representing Kernel-E parse trees.
the javadoc of the beginnings of a minimal set of XML DOM tree classes,
derived from org.w3c.dom by removing all the crap. As with normal
s-expressions, qdom supports only immutable trees that know their children
but not their parents. Therefore they can be shared. However, qdom trees
should be able to faithfully represent all of XML, just as dom trees do. I
will be extending these to support quasi-literals in support of
http://www.erights.org/elang/grammar/quasi-xml.html (hence the name "qdom").
I expect to initially use qdom trees for just two things:
* For Kernel-E parse trees in support of compilation to Java (along the
lines explained by http://www.erights.org/elang/kernel/index.html ) and
eventually C++ (as explained by the ENative pages
* To debug subsystems that uses Java Object Serialization Streams, such as
the in-progress revamping of the old "proxy comm" system. I've looked on
the web, and I *can't believe* that no one's written a program to parse a
JOSS stream it order to print an equivalent textual description, and that no
one's written something to take such a textual description and generate a
JOSS. However, I've looked on the web and couldn't find anything. Given
today's fads, the natural thing to do is define a DTD for the JOSS format,
and write converters from JOSS into this XML, and vice versa. If Javasoft
had done this a year ago, we would probably not be hearing about XML-RPC or
Does anyone have any opinions of MinML http://wilson.co.uk/xml/minml.htm , a
vastly smaller XML parser than the "standard" stuff (like Apache's Xerces or
Sun's Project-x)? Are there other reasonable small open-source parsers or
dom-tree classes out there?
Tyler, I recall you were doing some XML stuff, but I could find it among the
code I downloaded from you?
