<H2>Introduction</H2>
|
|
|
|
<P>Mini-XML is a small XML parsing library that you can use to
|
|
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'
|
|
ANSI C compilers) and a "make" program.
|
|
|
|
<P>Mini-XML was created to support the basic hierarchy provided
|
|
by XML and some simple data types, but doesn't do validation or
|
|
other types of processing on the data.
|
|
|
|
<H2>Building Mini-XML</H2>
|
|
|
|
<P>Mini-XML comes with an autoconf-based configure script; just
|
|
type the following command to get things going:
|
|
|
|
<PRE>
|
|
./configure
|
|
</PRE>
|
|
|
|
<P>The default install prefix is /usr/local, which can be
|
|
overridden using the --prefix option:
|
|
|
|
<PRE>
|
|
./configure --prefix=/foo
|
|
</PRE>
|
|
|
|
<P>Once you have configured the software, type "make" to do the
|
|
build and then run the test program to verify that things are
|
|
working, as follows:
|
|
|
|
<PRE>
|
|
make
|
|
./testmxml test.xml
|
|
</PRE>
|
|
|
|
<H2>Installing Mini-XML</H2>
|
|
|
|
<P>The "install" target will install Mini-XML in the lib and
|
|
include directories:
|
|
|
|
<PRE>
|
|
make install
|
|
</PRE>
|
|
|
|
<P>Once you have installed it, use the "-lmxml" option to link
|
|
your application against it.
|
|
|
|
<H2>Documentation</H2>
|
|
|
|
<P>The documentation is currently just in this page. At
|
|
some point I'll probably do some proper documentation, but
|
|
for now just read here and look at the testmxml.c source
|
|
file for an example of reading and printing the contents of
|
|
an XML file to stdout.
|
|
|
|
<P>Mini-XML provides a single header file which you include:
|
|
|
|
<PRE>
|
|
#include <mxml.h>
|
|
</PRE>
|
|
|
|
<P>Nodes are defined by the "mxml_node_t" structure; the "type"
|
|
member defines the node type (element, integer, opaque,
|
|
real, or text) which determines which value you want to look
|
|
at in the "value" union. New nodes can be created using the
|
|
"mxmlNewElement()", "mxmlNewInteger()", "mxmlNewOpaque()",
|
|
"mxmlNewReal()", and "mxmlNewText()" functions. Only
|
|
elements can have child nodes, and the top node must be an
|
|
element, usually "?xml".
|
|
|
|
<P>You load an XML file using the "mxmlLoadFile()" function:
|
|
|
|
<PRE>
|
|
FILE *fp;
|
|
mxml_node_t *tree;
|
|
|
|
fp = fopen("filename.xml", "r");
|
|
tree = mxmlLoadFile(NULL, fp, MXML_NO_CALLBACK);
|
|
fclose(fp);
|
|
</PRE>
|
|
|
|
<P>Similarly, you save an XML file using the "mxmlSaveFile()"
|
|
function:
|
|
|
|
<PRE>
|
|
FILE *fp;
|
|
mxml_node_t *tree;
|
|
|
|
fp = fopen("filename.xml", "w");
|
|
mxmlSaveFile(tree, fp);
|
|
fclose(fp);
|
|
</PRE>
|
|
|
|
<P>You can find a named element/node using the
|
|
"mxmlFindElement()" function:
|
|
|
|
<PRE>
|
|
mxml_node_t *node = mxmlFindElement(tree, tree, "name");
|
|
</PRE>
|
|
|
|
<P>You can also iterate with the same function:
|
|
|
|
<PRE>
|
|
mxml_node_t *node;
|
|
|
|
for (node = mxmlFindElement(tree, tree, "name");
|
|
node != NULL;
|
|
node = mxmlFindElement(node, tree, "name"))
|
|
{
|
|
... do something ...
|
|
}
|
|
</PRE>
|
|
|
|
<P>Finally, once you are done with the XML data, use the
|
|
"mxmlDelete()" function to free the memory that is used:
|
|
|
|
<PRE>
|
|
mxmlDelete(tree);
|
|
</PRE>
|
|
|
|
<H2>Getting Help and Reporting Problems</H2>
|
|
|
|
<P>You can email me at "mxml <I>at</I> easysw <I>dot</I> com" to
|
|
report problems and/or ask for help. Just don't expect an
|
|
instant response, as I get a *lot* of email...
