请有人向我显示一个使用libxml解析一些
HTML的简单示例.
#import
NSString *html = @"
"
""
""
""Hello World 1"
"Hello World 2";
1)说我想解析name = input2的输入的值.
应输出“string2value”.
2)说我想解析每个跨标签的class = spantext的内容.
应输出:“Hello World 1”和“Hello World 2”.
我使用本里维斯
HTML Parser来实现我想要的:
NSError *error = nil;
NSString *html =
@"
"
""
""
""Hello World 1"
"Hello World 2";
HTMLParser *parser = [[HTMLParser alloc] initWithString:html error:&error];
if (error) {
NSLog(@"Error: %@",error);
return;
}
HTMLNode *bodyNode = [parser body];
NSArray *inputNodes = [bodyNode findChildTags:@"input"];
for (HTMLNode *inputNode in inputNodes) {
if ([[inputNode getAttributeNamed:@"name"] isEqualToString:@"input2"]) {
NSLog(@"%@",[inputNode getAttributeNamed:@"value"]); //Answer to first question
}
}
NSArray *spanNodes = [bodyNode findChildTags:@"span"];
for (HTMLNode *spanNode in spanNodes) {
if ([[spanNode getAttributeNamed:@"class"] isEqualToString:@"spantext"]) {
NSLog(@"%@",[spanNode allContents]); //Answer to second question
}
}
[parser release];
