LibXML2.dylib 和 Xcode4

使用LibXML2.dylib和Xcode4进行XML解析

objective-c
#import 
// 创建XML解析器
xmlParserCtxtPtr parser = xmlNewParserCtxt();

objective-c
// 获取XML文件路径
NSString *xmlFilePath = [[NSBundle mainBundle] pathForResource:@"example" ofType:@"xml"];
// 加载XML文件到解析器
const char *xmlFile = [xmlFilePath UTF8String];
xmlDocPtr document = xmlCtxtReadFile(parser, xmlFile, NULL, XML_PARSE_NOBLANKS);
// 开始解析XML文件
xmlNodePtr rootNode = xmlDocGetRootElement(document);

objective-c
// 遍历XML节点
xmlNodePtr currentNode = rootNode;
while (currentNode != NULL) {
    if (currentNode->type == XML_ELEMENT_NODE) {
        // 处理当前节点
        // ...
    }
    currentNode = currentNode->next;
}

objective-c
// 提取节点数据
NSString *nodeName = [NSString stringWithUTF8String:(const char *)currentNode->name];
NSString *nodeValue = @"";
if (currentNode->children != NULL && currentNode->children->type == XML_TEXT_NODE) {
    xmlChar *text = xmlNodeListGetString(document, currentNode->children, 1);
    nodeValue = [NSString stringWithUTF8String:(const char *)text];
    xmlFree(text);
}

objective-c
// 释放资源
xmlFreeDoc(document);
xmlFreeParserCtxt(parser);
