tinyXml直接解析XML字符串

一直都用tinyxml直接LoadFile来解析XML，发现原来也可以直接解析XML字符串。

XML文件：

1 <?xml version="1.0" encoding="utf-8"?>
2 <person>
3     <name>Alan</name>
4     <age>26</age>
5     <height>165</height>
6     <weight>65</weight>
7     <introduction>C senior engineer</introduction>
8 </person>

解析代码：

 1 #include <stdio.h>
 2 #include "tinyxml.h"
 3 
 4 int tinyxmlTest(void);
 5 
 6 int main(int argc, char* argv[])
 7 {
 8     tinyxmlTest();
 9     return 1;
10 }
11 
12 int tinyxmlTest(void)
13 {
14 #if (1)
15     char* xmlStr = "
16 <person>
17     <name>Alan</name>
18     <age>26</age>
19     <height>165</height>
20     <weight>65</weight>
21     <introduction>C senior engineer</introduction>
22 </person>";
23     
24     TiXmlDocument* myDocument = new TiXmlDocument();
25     myDocument->Parse(xmlStr);
26 
27 #else
28     TiXmlDocument* myDocument = new TiXmlDocument();
29   myDocument->LoadFile("person.xml");
30 #endif
31     //.....person.....
32   TiXmlElement* rootElement = myDocument->RootElement();
33     if (rootElement == NULL || strcmp(rootElement->Value(), "person"))
34         return 0;
35     printf("%s:	%s
", rootElement->Value(), rootElement->GetText());
36 
37     //.....name.....
38   TiXmlElement* element = rootElement->FirstChildElement();
39     if (element == NULL || strcmp(element->Value(), "name"))
40         return 0;
41     printf("%s:	%s
", element->Value(), element->GetText());
42 
43     //.....age.....
44     element = element->NextSiblingElement();
45     if (element == NULL || strcmp(element->Value(), "age"))
46         return 0;
47     printf("%s:	%s
", element->Value(), element->GetText());
48     
49     //.....height.....
50     element = element->NextSiblingElement();
51     if (element == NULL || strcmp(element->Value(), "height"))
52         return 0;
53     printf("%s:	%s
", element->Value(), element->GetText());
54 
55     //.....weight.....
56     element = element->NextSiblingElement();
57     if (element == NULL || strcmp(element->Value(), "weight"))
58         return 0;
59     printf("%s:	%s
", element->Value(), element->GetText());
60 
61     //.....introduction.....
62     element = element->NextSiblingElement();
63     if (element == NULL || strcmp(element->Value(), "introduction"))
64         return 0;
65     printf("%s:	%s

", element->Value(), element->GetText());
66 
67     return 1;
68 }

顺便推荐其他博友对tinyxml使用介绍
