使用XPath轻松获得VC9.0工程文件包含的所有代码文件

玩了几天空之轨迹 FC，终于快结束了。距离最后一门考试还有3天，于是把整个XPath的代码写完了。于是试用一下。

现在展示一下我那个XPath的使用方法：

1     VL_List < VL_XMLNode * , true > Result;
2     VL_XPath XPath(L " //Files//File[contains(@RelativePath,\ " .cpp\ " ) or contains(@RelativePath,\ " .h\ " )] " );
3     XPath.Query(Doc.GetRootElement(),Result);

    第一行声明一个XML节点列表，第二行构造一个XPath，第三行将XPath作用在一个XML文档的根节点上。这个XPath用于把VC++9.0的工程文件中包含的所有.h文件和.cpp文件提取出来。虽然Files里面包含若干Filter，每一个Filter包含一些Filter和File，不过输出结果Output.xml把所有的满足要求的File节点都找了出来。

    下面是完整的代码，包含输入输出、一份vcproj文件和一份结果的XML：
    首先是C++代码：

#include "..\..\..\..\Library\Platform\VL_Console.h"

#include "..\..\..\..\Library\Data\VL_System.h"

#include "..\..\..\..\Library\Data\VL_Stream.h"

#include "..\..\..\..\Library\XML\VL_XML.h"

using namespace vl;

using namespace vl::platform;

using namespace vl::system;

using namespace vl::stream;

using namespace vl::xml;

void vlmain(VL_Console& Con)

{

Con.SetPauseOnExit(false);

Con.SetTestMemoryLeaks(true);

Con.SetTitle(L"Vczh XML");

/*设置输入输出文件*/

VUnicodeString AppPath=VFileName(Con.GetAppPath()).MakeAbsolute(L"..\\").GetStrW();

VUnicodeString InputFile=AppPath+L"Input.xml";

VUnicodeString OutputFile=AppPath+L"Output.xml";

/*载入Input.xml*/

VL_XMLDocument Doc;

{

VL_FileInputStream Stream(InputFile);

Doc.Load(&Stream);

}

/*使用XPath对根节点进行搜索*/

VL_List<VL_XMLNode* , true> Result;

VL_XPath XPath(L"//Files//File[contains(@RelativePath,\".cpp\") or contains(@RelativePath,\".h\")]");

XPath.Query(Doc.GetRootElement(),Result);

/*将搜索到的attribute和其他节点分开*/

VUnicodeString OutputAttributes;

VUnicodeString OutputNodes;

for(VInt i=0;i<Result.GetCount();i++)

{

if(Result[i]->GetAttribute())

{

OutputAttributes+=L"<attribute "+Result[i]->GetXMLText()+L"/>";

}

else

{

OutputNodes+=L"<node>"+Result[i]->GetXMLText()+L"</node>";

}

/*将结果保存到Output.xml*/

VL_TextOutput(new VL_FileOutputStream(OutputFile,false),true,vceMbcs,true).Write

(L"<?xml version=\"1.0\" encoding=\"gb2312\" standalone=\"yes\"?><result><attributes>"

+OutputAttributes

+L"</attributes><nodes>"

+OutputNodes

+L"</nodes></result>"

);

}

其次是vcproj文件（Input.xml）：

<? xml version="1.0" encoding="gb2312" ?>
