Objective-C-HMTL-Parser 是一个用 ObjectiveC 编写的简易 HTML 解析器。
示例代码：
NSError *error = nil; NSString *html = @"<ul>" "<li><input type='image' name='input1' value='string1value' /></li>" "<li><input type='image' name='input2' value='string2value' /></li>" "</ul>" "<span class='spantext'><b>Hello World 1</b></span>" "<span class='spantext'><b>Hello World 2</b></span>"; 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 rawContents]); //Answer to second question } } [parser release];
