迷你型XML文档生成器(ANSI C)
最近做嵌入式项目，需要生成XML状态报文，C++的XML的解析器就不能用了。然后使用xmllib2，功能挺多，也很稳定，就是太大了，不利于移植到ARM，而且有很多的功能用不上，编译部署麻烦。一日，看了一本书上好像这么说： 一个工具解决的问题比它引入的问题还多，就去掉它，重新从零开始。感觉说得的有道理，我还不如自己写一个。Forge....
花了一下午，共200行C代码完成了一个XML文档生成器，测试了一下效率相当高，也很稳定，感觉好极了。那位大哥如果能做的更精巧，不妨提携一下小弟，不吝指教。
工程名称：MiniXML
工程下载： http://www.cppblog.com/Files/dyj057/minixml.zip
在XP+VS2003中编译通过，你也可以在Linux,Unix上使用。
使用例子：
xmlNodePtr child;
xmlNodePtr nameNode ;
xmlDocPtr doc = xmlNewDoc();
doc -> root = xmlNewNode( " employees " );
child = xmlAddChild(doc -> root, xmlNewNode( " employee " ));
xmlAddProp(child, " age " , " 28 " );
xmlAddProp(child, " sexy " , " male " );
nameNode = xmlAddChild(child, xmlNewNode( " name " ));
xmlAddText(nameNode, xmlNewText( " Nicholas C. Zakas " ));
child = xmlAddChild(doc -> root, xmlNewNode( " employee " ));
xmlAddProp(child, " age " , " 22 " );
xmlAddProp(child, " sexy " , " male " );
nameNode = xmlAddChild(child, xmlNewNode( " name " ));
xmlAddText(nameNode, xmlNewText( " Jim Smith " ));
printfXmlDoc(stdout,doc);
xmlFreeDoc(doc);
xmlNodePtr nameNode ;
xmlDocPtr doc = xmlNewDoc();
doc -> root = xmlNewNode( " employees " );
child = xmlAddChild(doc -> root, xmlNewNode( " employee " ));
xmlAddProp(child, " age " , " 28 " );
xmlAddProp(child, " sexy " , " male " );
nameNode = xmlAddChild(child, xmlNewNode( " name " ));
xmlAddText(nameNode, xmlNewText( " Nicholas C. Zakas " ));
child = xmlAddChild(doc -> root, xmlNewNode( " employee " ));
xmlAddProp(child, " age " , " 22 " );
xmlAddProp(child, " sexy " , " male " );
nameNode = xmlAddChild(child, xmlNewNode( " name " ));
xmlAddText(nameNode, xmlNewText( " Jim Smith " ));
printfXmlDoc(stdout,doc);
xmlFreeDoc(doc);
生成XML文档如下：
<?xml version="1.0" encoding="utf-8"?>
<employees>
<employee age="28" sexy="male">
<name>Nicholas C. Zakas</name>
</employee>
<employee age="22" sexy="male">
<name>Jim Smith</name>
</employee>
</employees>
