New versions of expat will be available from <A href="http://expat.sourceforge.net">expat.sourceforge.net</A>.</p> <H4>Where can I get help in using expat?</H4> <p>Try the xml-dev mailing list (subscribe by mailing to <a href="mailto:majordomo@xml.org&BODY=subscribe%20xml-dev">majordomo@xml.org</a> with the message <code>subscribe xml-dev</code>). Alternatively try the mailing lists hosted by <A href="http://expat.sourceforge.net">sourceforge.net</A>.</P> <H4>Where is expat's API documented?</H4> <p>In <code>xmlparse/xmlparse.h</code>. There's also an advanced, low-level API you can use which is documented in <code>xmltok/xmltok.h</code>.</p> <p>There's also an excellent <a href="http://www.xml.com/pub/1999/09/expat/index.html">article</a> about expat on XML.com by Clark Cooper.</p> <H4>Is there a simple example of using expat's API?</H4> <p>See <code>sample/elements.c</code></p> <H4>How can I get expat to deal with non-ASCII characters?</H4> <P>By default, expat assumes that documents are encoded in UTF-8. In UTF-8, ASCII characters are represented by a single byte as they would be in ASCII, but non-ASCII characters are represented by a sequence of two or more bytes all with the 8th bit set. The encoding most widely used for European languages is ISO 8859-1 which is not compatible with UTF-8. To use this encoding, expat must be told either by supplying an argument of <code>"iso-8859-1"</code> to <code>XML_ParserCreate</code>, or by starting the document with <code><?xml version="1.0" encoding="iso-8859-1"?></code>.</P> <H4>What encodings does expat support?</H4> <P>expat has built in support for the following encodings:</P> <ul> <li><code>utf-8</code></li> <li><code>utf-16</code></li> <li><code>iso-8859-1</code></li> <li><code>us-ascii</code></li> </ul> <P>Additional encodings can be supported by using <code>XML_SetUnknownEncodingHandler</code>.</P> <H4>How can I get expat to validate my XML documents?</H4> <p>You can't. expat is not a validating parser.</p> <H4>How can I get expat to read my DTD?</H4> <p>Compile with <code>-DXML_DTD</code> and call <code>XML_SetParamEntityParsing</code>.</p> <H4>How can I get expat to recover from errors?</H4> <p>You can't. All well-formedness errors stop processing. Note that the XML Recommendation does not permit conforming XML processors to continue normal processing after a fatal error.</p> <H4>How do I get at the characters between tags?</H4> <p>Use <code>XML_SetCharacterDataHandler</code>.</p> <H4>How can I minimize the size of expat?</H4> <p>Compile with <code>-DXML_MIN_SIZE</code>. With Visual C++, use the <code>Win32 MinSize</code> configuration: this creates an <code>xmlparse.dll</code> that does not require <code>xmltok.dll</code>.</p> <ADDRESS> <A HREF="mailto:jjc@jclark.com">James Clark</A> </ADDRESS> </BODY> </HTML>
