Objective-C-HTML-ParseriOS 简易 HTML 解析器

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];
