tinyxml动态库生成和使用

1、xml默认是生成执行文件，要想生成动态库需要修改makefile

从http://ncu.dl.sourceforge.net/sourceforge/tinyxml/tinyxml_2_4_0.tar.gz下载tinyxml，可以根据自己的需要，选择不同的版本。

将tinyxml_2_4_0.tar.gz上传到主机，然后解压执行如下命令:

 tar -xzvf tinyxml_2_4_0.tar.gz

成功之后，会在当前目录出现一个tinyxml目录,进入该目录cd tinyxml,然后进行编译，顺序执行如下命令:

cd tinyxml

make

在屏幕上会打印如下输出：

 [dev@localhost tinyxml]$ make
 g++ -c -Wall -Wno-format -g -DDEBUG    tinyxml.cpp -o tinyxml.o
 g++ -c -Wall -Wno-format -g -DDEBUG    tinyxmlparser.cpp -o tinyxmlparser.o
 g++ -c -Wall -Wno-format -g -DDEBUG    xmltest.cpp -o xmltest.o
 g++ -c -Wall -Wno-format -g -DDEBUG    tinyxmlerror.cpp -o tinyxmlerror.o
 g++ -c -Wall -Wno-format -g -DDEBUG    tinystr.cpp -o tinystr.o
 tinystr.cpp:38: warning: aggregate has a partly bracketed initializer
 g++ -o xmltest -g tinyxml.o tinyxmlparser.o xmltest.o tinyxmlerror.o tinystr.o

没有出现错误，表示编译完成，这时可以执行tinyxml自带的测试程序xmltest。

我直行xmltest之后，打印出一堆乱码，后来就没有管。自己写程序测试了。

 

为了使用tinyxml开发，使用方便，做了一些配置。

添加环境变量TINYXML_ROOT,编辑.bash_profile，添加如下内容：

 #############################################
 #### for tinyxml
 #############################################
 export TINYXML_ROOT=$HOME/tinyxml

把tinyxml包编译打包成一个连接库，方便开发，这就要修改tinyxml目录下的Makefile。

 tinyxmlparser.o: tinyxml.h tinystr.h
 xmltest.o: tinyxml.h tinystr.h
 tinyxmlerror.o: tinyxml.h tinystr.h

在tinyxml目录下重新执行make，会看到多执行了一行命令：

ar -r libtinyxml.so tinyxml.o tinyxmlparser.o tinyxmlerror.o tinystr.o

生成了一个包libtinyxml.so，有了这个包，使用tinyxml开发的时候，在连接命令中加入这个包的连接，就可以正确地生成目标程序。

2、使用tinyxml库

TinyXML是一个开源的解析XML的解析库，能够用于C++，能够在Windows或Linux中编译。这个解析库的模型通过解析XML文件，然后在内存中生成DOM模型，从而让我们很方便的遍历这棵XML树。

    DOM模型即文档对象模型，是将整个文档分成多个元素（如书、章、节、段等），并利用树型结构表示这些元素之间的顺序关系以及嵌套包含关系。
    首先从网上下载TinyXML的库，文件夹的名字是TinyXpath，在工程里做如下配置：
    在附加包含路径里添加：你的tinyxpath路径/tinyxpath/include
    在附加库路径里添加：你的tinyxpath路径/tinyxpath/lib
    在对象/库路径里添加：tinyxpathd.lib，如果使用release版本，则是tinyxpath.lib。
    另外，由于我开发的项目是多线程的，所以设置了多线程的环境，因此使用TinyXML没有出现问题。本人将TinyXML写在一个单独的C++工程进行测试，发现如果不设置多线程的环境，会出现链接错误。我觉得原因可能是TinyXML使用了多线程环境，因此需要设置 多线程的环境。在工程/设置下的C/C++选项卡中，选择Code Generation，在Use run-time library中选择Debug MultiThreaed DLL即可。

     使用Parse函数就可以解析XML字符流了，这是很多开发者不太熟悉的情况。

    如果开发者开发特定应用，就可以使用上述类似方法，可能不需要完全处理每一个属性，比如可以对属性名进行判断，只处理自己需要的属性，或者自己需要的xml元素。还可以使用TinyXML的方法创建xml元素和xml属性，或者设置xml元素和属性对应的值，等等，如果读者想要类似的例子，可以留言写出。
      下面介绍TinyXML的一些类。在TinyXML中，根据XML的各种元素来定义了一些类：
           TiXmlBase：整个TinyXML模型的基类。

TiXmlAttribute：对应于XML中的元素的属性。

TiXmlNode：对应于DOM结构中的节点。

TiXmlComment：对应于XML中的注释

TiXmlDeclaration：对应于XML中的申明部分，<？versiong="1.0" ?>。

TiXmlDocument：对应于XML的整个文档。

TiXmlElement：对应于XML的元素。

TiXmlText：对应于XML的文字部分

TiXmlUnknown：对应于XML的未知部分。 

        TiXmlHandler：定义了针对XML的一些操作。

3、linux中动态库的使用

编译生产libcac.so文件如下：  gcc -shared -fPIC caculate.c -o libcac.so

编译生产可执行文件main如下：gcc main.c -o main -L ./ -lcac   （其中-L指明动态链接库的路径，-l后是链接库的名称，省略lib）
