xml解析与生成工具mini-xml移植与使用

mini-xml是c语音实现的xml生成与解析库，适合在纯c开发的嵌入式开发使用。

获取mini-xml源码

http://www.minixml.org/software.php下载libmxml库文件

编译mini-xml静态库

1. 解压下载的源代码，配置编译工具

./configure --host=arm-hisiv300-linux

2. 修改生产了Makefile文件
   将OBJS = mmd.o mxmldoc.o testmxml.o zipc.o $(LIBOBJS)
   修改为：OBJS = mmd.o $(LIBOBJS)

   在all: $(TARGETS) 行后增加如下内容：
   $(AR) -r libmxml.a $(OBJS)

3. make编译，生成libmxml.a文件

使用mini-xml

1. 编译使用mini-xml库自带的testmxml.c

gcc -o testmxml testmxml.c -lmxml -lpthread

2. 编写自定义测试程序mymxml_test.c

#include <stdio.h>
#include <string.h>
#include "mxml.h"
