<h2>Introduction</h2>
|
|
|
|
|
|
|
|
|
|
<p>Mini-XML is a small XML parsing library that you can use to
|
2003-06-03 19:46:29 +00:00
|
|
|
read XML and XML-like data files in your application without
|
|
|
|
|
requiring large non-standard libraries. Mini-XML only requires
|
|
|
|
|
an ANSI C compatible compiler (GCC works, as do most vendors'
|
2003-06-04 16:30:40 +00:00
|
|
|
ANSI C compilers) and a "make" program.</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>Mini-XML was created to support the basic hierarchy provided
|
2003-06-03 19:46:29 +00:00
|
|
|
by XML and some simple data types, but doesn't do validation or
|
2003-06-04 16:30:40 +00:00
|
|
|
other types of processing on the data.</p>
|
2003-06-03 19:46:29 +00:00

<h2>Building Mini-XML</h2>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>Mini-XML comes with an autoconf-based configure script; just
|
|
|
|
|
type the following command to get things going:</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<pre>
|
2003-06-03 19:46:29 +00:00
|
|
|
./configure
|
2003-06-04 16:30:40 +00:00
|
|
|
</pre>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>The default install prefix is /usr/local, which can be
|
|
|
|
|
overridden using the --prefix option:</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<pre>
|
2003-06-03 19:46:29 +00:00
|
|
|
./configure --prefix=/foo
|
2003-06-04 16:30:40 +00:00
|
|
|
</pre>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>Once you have configured the software, type "make" to do the
|
2003-06-03 19:46:29 +00:00
|
|
|
build and then run the test program to verify that things are
|
2003-06-04 16:30:40 +00:00
|
|
|
working, as follows:</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00

<pre>

2003-06-03 19:46:29 +00:00

make

./testmxml test.xml

<h2>Installing Mini-XML</h2>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>The "install" target will install Mini-XML in the lib and
|
|
|
|
|
include directories:</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<pre>
|
2003-06-03 19:46:29 +00:00
|
|
|
make install
|
2003-06-04 16:30:40 +00:00
|
|
|
</pre>

2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>Once you have installed it, use the "-lmxml" option to link
|
|
|
|
|
your application against it.</p>

<h2>Documentation</h2>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>The documentation is currently just in this page. At some
|
2003-06-03 20:24:28 +00:00
|
|
|
point I'll probably do some proper documentation, but for now
|
2003-06-04 16:30:40 +00:00
|
|
|
just read here and look at the <tt><a
|
|
|
|
|
href="testmxml.c">testmxml.c</a></tt> source file for an
|
2003-06-03 20:24:28 +00:00
|
|
|
example of reading and printing the contents of an XML file to
|
2003-06-04 16:30:40 +00:00
|
|
|
stdout.</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>Mini-XML provides a single header file which you include:</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<pre>
|
|
|
|
|
<a href="mxml.h">#include <mxml.h></a>
|
|
|
|
|
</pre>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>Nodes are defined by the <tt>mxml_node_t</tt> structure; the
|
|
|
|
|
<tt>type</tt> member defines the node type (element, integer,
|
2003-06-03 20:24:28 +00:00
|
|
|
opaque, real, or text) which determines which value you want to
|
2003-06-04 16:30:40 +00:00
|
|
|
look at in the <tt>value</tt> union. New nodes can be created
|
|
|
|
|
using the <tt>mxmlNewElement()</tt>, <tt>mxmlNewInteger()</tt>,
|
|
|
|
|
<tt>mxmlNewOpaque()</tt>, <tt>mxmlNewReal()</tt>, and
|
|
|
|
|
<tt>mxmlNewText()</tt> functions. Only elements can have child
|
|
|
|
|
nodes, and the top node must be an element, usually "?xml".</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>You load an XML file using the <tt>mxmlLoadFile()</tt> function:</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<pre>
|
2003-06-03 19:46:29 +00:00
|
|
|
FILE *fp;
|
|
|
|
|
mxml_node_t *tree;
|
|
|
|
|
|
|
|
|
|
fp = fopen("filename.xml", "r");
|
|
|
|
|
tree = mxmlLoadFile(NULL, fp, MXML_NO_CALLBACK);
|
|
|
|
|
fclose(fp);
|
2003-06-04 16:30:40 +00:00

</pre>

|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>Similarly, you save an XML file using the <tt>mxmlSaveFile()</tt>
|
|
|
|
|
function:</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00

<pre>

2003-06-03 19:46:29 +00:00
|
|
|
FILE *fp;

|
|
|
|
mxml_node_t *tree;
|
|
|
|
|
|
|
|
|
|
fp = fopen("filename.xml", "w");
|
|
|
|
|
mxmlSaveFile(tree, fp);
|
|
|
|
|
fclose(fp);
|
2003-06-04 16:30:40 +00:00

|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>You can find a named element/node using the
|
|
|
|
|
<tt>mxmlFindElement()</tt> function:</p>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<pre>
|
|
|
|
|
mxml_node_t *node = mxmlFindElement(tree, tree, "name", "attr",
|
|
|
|
|
"value", MXML_DESCEND);
|
|
|
|
|
</pre>
|
2003-06-03 19:46:29 +00:00
|
|
|
|
2003-06-04 16:30:40 +00:00
|
|
|
<p>The <tt>name</tt>, <tt>attr</tt>, and <tt>value</tt>
|
|
|
|
|
arguments can be passed as <tt>NULL</tt> to act as wildcards,
|
|
|
|
|
e.g.:</p>

node = mxmlFindElement(tree, tree, "a", NULL, NULL, MXML_DESCEND);

|
|
|

</pre>
|

|
|
|

<p>You can also iterate with the same function:</p>

<p>Finally, once you are done with the XML data, use the
|
|
|
|
|
<tt>mxmlDelete()</tt> function to recursively free the memory

that is used for a particular node or the entire tree:</p>
