| 2 | Expat, Release 2.0.0 |
| 3 | |
| 4 | This is Expat, a C library for parsing XML, written by James Clark. |
| 5 | Expat is a stream-oriented XML parser. This means that you register |
| 6 | handlers with the parser before starting the parse. These handlers |
| 7 | are called when the parser discovers the associated structures in the |
| 8 | document being parsed. A start tag is an example of the kind of |
| 9 | structures for which you may register handlers. |
| 10 | |
| 11 | Windows users should use the expat_win32bin package, which includes |
| 12 | both precompiled libraries and executables, and source code for |
| 13 | developers. |
| 14 | |
| 15 | Expat is free software. You may copy, distribute, and modify it under |
| 16 | the terms of the License contained in the file COPYING distributed |
| 17 | with this package. This license is the same as the MIT/X Consortium |
| 18 | license. |
| 19 | |
| 20 | Versions of Expat that have an odd minor version (the middle number in |
| 21 | the release above), are development releases and should be considered |
| 22 | as beta software. Releases with even minor version numbers are |
| 23 | intended to be production grade software. |
| 24 | |
| 25 | If you are building Expat from a check-out from the CVS repository, |
| 26 | you need to run a script that generates the configure script using the |
| 27 | GNU autoconf and libtool tools. To do this, you need to have |
| 28 | autoconf 2.52 or newer and libtool 1.4 or newer. Run the script like |
| 29 | this: |
| 30 | |
| 31 | ./buildconf.sh |
| 32 | |
| 33 | Once this has been done, follow the same instructions as for building |
| 34 | from a source distribution. |
| 35 | |
| 36 | To build Expat from a source distribution, you first run the |
| 37 | configuration shell script in the top level distribution directory: |
| 38 | |
| 39 | ./configure |
| 40 | |
| 41 | There are many options which you may provide to configure (which you |
| 42 | can discover by running configure with the --help option). But the |
| 43 | one of most interest is the one that sets the installation directory. |
| 44 | By default, the configure script will set things up to install |
| 45 | libexpat into /usr/local/lib, expat.h into /usr/local/include, and |
| 46 | xmlwf into /usr/local/bin. If, for example, you'd prefer to install |
| 47 | into /home/me/mystuff/lib, /home/me/mystuff/include, and |
| 48 | /home/me/mystuff/bin, you can tell configure about that with: |
| 49 | |
| 50 | ./configure --prefix=/home/me/mystuff |
| 51 | |
| 52 | Another interesting option is to enable 64-bit integer support for |
| 53 | line and column numbers and the over-all byte index: |
| 54 | |
| 55 | ./configure CPPFLAGS=-DXML_LARGE_SIZE |
| 56 | |
| 57 | After running the configure script, the "make" command will build |
| 58 | things and "make install" will install things into their proper |
| 59 | location. Have a look at the "Makefile" to learn about additional |
| 60 | "make" options. Note that you need to have write permission into |
| 61 | the directories into which things will be installed. |
| 62 | |
| 63 | If you are interested in building Expat to provide document |
| 64 | information in UTF-16 rather than the default UTF-8, follow these |
| 65 | instructions: |
| 66 | |
| 67 | 1. For UTF-16 output as unsigned short (and version/error |
| 68 | strings as char), run: |
| 69 | |
| 70 | ./configure CPPFLAGS=-DXML_UNICODE |
| 71 | |
| 72 | For UTF-16 output as wchar_t (incl. version/error strings), |
| 73 | run: |
| 74 | |
| 75 | ./configure CFLAGS="-g -O2 -fshort-wchar" \ |
| 76 | CPPFLAGS=-DXML_UNICODE_WCHAR_T |
| 77 | |
| 78 | 2. Edit the MakeFile, changing: |
| 79 | |
| 80 | LIBRARY = libexpat.la |
| 81 | |
| 82 | to: |
| 83 | |
| 84 | LIBRARY = libexpatw.la |
| 85 | |
| 86 | (Note the additional "w" in the library name.) |
| 87 | |
| 88 | 3. Run "make buildlib" (which builds the library only). |
| 89 | |
| 90 | 4. Run "make installlib" (which installs the library only). |
| 91 | |
| 92 | Note for Solaris users: The "ar" command is usually located in |
| 93 | "/usr/ccs/bin", which is not in the default PATH. You will need to |
| 94 | add this to your path for the "make" command, and probably also switch |
| 95 | to GNU make (the "make" found in /usr/ccs/bin does not seem to work |
| 96 | properly -- appearantly it does not understand .PHONY directives). If |
| 97 | you're using ksh or bash, use this command to build: |
| 98 | |
| 99 | PATH=/usr/ccs/bin:$PATH make |
| 100 | |
| 101 | When using Expat with a project using autoconf for configuration, you |
| 102 | can use the probing macro in conftools/expat.m4 to determine how to |
| 103 | include Expat. See the comments at the top of that file for more |
| 104 | information. |

| 107 | distribution. |
