Re: Socket/kernel interaction
Posted by Joseph Kesselman <ke...@us.ibm.com>.
In the Java version, Xalan and Xerces generally run in the same process. I
would expect that to be true in the C++ version as well.
Of course we may wind up having to perform net activity to retrieve data.
As you guessed, that's generally handled by Xerces rather than by Xalan.
In the Java version, we use the standard Java code for retrieving data
from a URI...

Hi Rishi,
I have no idea what you mean by "every page coming in."
Xerces is an XML parser. It parses and optionally validates XML documents.
If you want to build a smaller Xerces binary, then you might post a
question on the Xerces-C list, or search the archive to see if anyone else
has asked the question.

Hi David,
Is this DTD and schema validation done for every
page that comes in?
I was thinking if this a non-recurrent operation
this could be put in a separate library to reasonably
tweak the final binary size.
Thanks!

Hi Rishi,
Why do you think Xerces is "a parser which builds the parse tree based on
input from the stylesheet?" It's a full-featured XML parser that supports
DTD and schema validation, whcih is not a small piece of code. You may
want to run strip on the shared library, which will reduce the size a fair
amount.
The documentation as you see it is what there is. There is not much other
than documentation of the API. You can study the sample applications for
more information.

Hi David,
So I guess you are suggesting that Xalan interacts
with Xerces via library API calls...
After building Xerces2.1, I noticed the binary size to
be 3GB, more specifically 3112517 bytes. Wonder why is
the size so huge for a parser which just builds the
parse tree based on input from the stylesheet?
Any optimization you suggest? I shall mail this
question on the Xerces list as well.
I have to following as a reference to documentation.
http://xml.apache.org/xalan-c/apidocs/classes.html
http://xml.apache.org/xerces-c/apiDocs/index.html
Any suggestions on how to go about these? Is there
some sort of verbal documentation describing the

Thanks for the lead about classes that implement http

Hi Rishi,
There is no IPC between Xerces and Xalan.
Xerces has some classes that implement http access for URLs. Take a look
at the documentation for more information. You could also post any
questions you have on the Xerces-C list.
Stating that XML "runs over TCP/IP" is misleading. XML documents can
transferred through a TCP/IP socket, but that's just one of many potential
communication channels.

Hi,

XML runs over TCP/IP. Which are the classes that deal

The Xalan1.4 Xerces2.1 combo works fine through

Any ideas?

You need the latest code from CVS or a recent CVS tarball to build Xalan
with Xerces 2.2. There are changes in Xerces 2.2 which are not backward
