<P>Copyright (c) 1998, 1999, 2000 Thai Open Source Software Center

Ltd. Expat is freely available with source under a very liberal <a
|
|
href="copying.txt">license</a> (the MIT license).</P>
|
|
|
|
<P>This is a test version of expat which adds support for parsing
|
|
external DTDs and parameter entities. Compiling with -DXML_DTD
|
|
enables this support. There's a new <CODE>-p</CODE> option for xmlwf
|
|
which will cause it to process external DTDs and parameter entities;
|
|
this implies the <CODE>-x</CODE> option. See the comment above
|
|
<CODE>XML_SetParamEntityParsing</CODE> in <CODE>xmlparse.h</CODE> for
|
|
the API addition that enables this.</P>
|
|
|
|
<P>Expat is an <A
|
|
HREF="http://www.w3.org/TR/1998/REC-xml-19980210">XML 1.0</A> parser
|
|
written in C. It aims to be fully conforming. It is currently not a
|
|
validating XML processor. The current production version of expat can
|
|
be downloaded from <A href =
|
|
"http://www.ThaiOpenSource.com/dist/expat/expat.zip"
|
|
>http://www.ThaiOpenSource.com/dist/expat/expat.zip</A>.</P>
|
|
|
|
<P>The directory <SAMP>xmltok</SAMP> contains a low-level library for
|
|
tokenizing XML. The interface is documented in
|
|
<SAMP>xmltok/xmltok.h</SAMP>.</P>
|
|
|
|
<P>The directory <SAMP>xmlparse</SAMP> contains an XML parser library
|
|
which is built on top of the <SAMP>xmltok</SAMP> library. The
|
|
interface is documented in <SAMP>xmlparse/xmlparse.h</SAMP>. The
|
|
directory <SAMP>sample</SAMP> contains a simple example program using
|
|
this interface; <SAMP>sample/build.bat</SAMP> is a batch file to build
|
|
the example using Visual C++.</P>
|
|
|
|
<P>The directory <SAMP>xmlwf</SAMP> contains the <SAMP>xmlwf</SAMP>
|
|
application, which uses the <SAMP>xmlparse</SAMP> library. The
|
|
arguments to <SAMP>xmlwf</SAMP> are one or more files which are each
|
|
to be checked for well-formedness. An option <SAMP>-d
|
|
<VAR>dir</VAR></SAMP> can be specified; for each well-formed input
|
|
file the corresponding <A
|
|
href="http://www.jclark.com/xml/canonxml.html">canonical XML</A> will
|
|
be written to <SAMP>dir/<VAR>f</VAR></SAMP>, where
|
|
<SAMP><VAR>f</VAR></SAMP> is the filename (without any path) of the
|
|
input file. A <CODE>-x</CODE> option will cause references to
|
|
external general entities to be processed. A <CODE>-s</CODE> option
|
|
will make documents that are not standalone cause an error (a document
|
|
is considered standalone if either it is intrinsically standalone
|
|
because it has no external subset and no references to parameter
|
|
entities in the internal subset or it is declared as standalone in the
|
|
XML declaration).</P>
|
|
|
|
<P>The <SAMP>bin</SAMP> directory contains Win32 executables. The
|
|
<SAMP>lib</SAMP> directory contains Win32 import libraries.</P>
