Expat is an XML 1.0 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 ftp://ftp.jclark.com/pub/xml/expat.zip.

The directory `xmltok` contains a low-level library for tokenizing XML. The interface is documented in `xmltok/xmltok.h`.

The directory `xmlparse` contains an XML parser library which is built on top of the `xmltok` library. The interface is documented in `xmlparse/xmlparse.h`. The directory `sample` contains a simple example program using this interface; `sample/build.bat` is a batch file to build the example using Visual C++.

The directory `xmlwf` contains the `xmlwf` application, which uses the `xmlparse` library. The arguments to `xmlwf` are one or more files which are each to be checked for well-formedness. An option `-d dir` can be specified; for each well-formed input file the corresponding canonical XML will be written to `dir/f`, where `f` is the filename (without any path) of the input file. A `-x` option will cause references to external general entities to be processed. A `-s` 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).

The `bin` directory contains Win32 executables. The `lib` directory contains Win32 import libraries.
