iPhone 上的 HTML 解析

我想解析这个网站：

http://its.wonju.go.kr /movinginfo2/DetailSub/StopDetail.asp?StopID=1959#

所以我尝试使用 TFHpple。像这样：

NSString *htmlWillInsert = [NSString stringWithContentsOfURL:
                            [NSURL URLWithString:@"http://its.wonju.go.kr/movinginfo2/DetailSub/StopDetail.asp?StopID=1959#"]
                                                    encoding:-2147481280
                                                       error:nil];

NSData *htmlData = [htmlWillInsert dataUsingEncoding:NSUnicodeStringEncoding];

TFHpple *xpathParser =[[TFHpple alloc] initWithHTMLData:htmlData];
NSArray *busNumbs = [xpathParser search:@"//td //a[@class='new']"];
NSLog (@"%@",busNumbs);

 for (int i=0;i<[busNumbs count];i++) {
    TFHppleElement *busNumb = [busNumbs objectAtIndex:i];
    NSString *Numb = [busNumb content];
    NSString *st = [[NSString alloc]initWithFormat:@"%@",Numb];
    NSLog(@"%@",st);
}

但它不起作用:(...

I want to parse this site :

http://its.wonju.go.kr/movinginfo2/DetailSub/StopDetail.asp?StopID=1959#

So I tried use TFHpple. Like this :

NSString *htmlWillInsert = [NSString stringWithContentsOfURL:
                            [NSURL URLWithString:@"http://its.wonju.go.kr/movinginfo2/DetailSub/StopDetail.asp?StopID=1959#"]
                                                    encoding:-2147481280
                                                       error:nil];

NSData *htmlData = [htmlWillInsert dataUsingEncoding:NSUnicodeStringEncoding];

TFHpple *xpathParser =[[TFHpple alloc] initWithHTMLData:htmlData];
NSArray *busNumbs = [xpathParser search:@"//td //a[@class='new']"];
NSLog (@"%@",busNumbs);

 for (int i=0;i<[busNumbs count];i++) {
    TFHppleElement *busNumb = [busNumbs objectAtIndex:i];
    NSString *Numb = [busNumb content];
    NSString *st = [[NSString alloc]initWithFormat:@"%@",Numb];
    NSLog(@"%@",st);
}

But it isn't working :(...
It loads<a href="#" onClick="MapMove(22);" class="new" onFocus='this.blur();'">▷ 22번(순환)
But It can't loads <font color='red'> 108분후 도착</font>

标签是锚标签的子节点。描述[aTFHppleElement content]被错误地描述作为innerHTML，因为它只包含元素的文本内容而不是其子节点的内容。因此，您需要访问子节点才能显示该信息。事实上，存储库中的代码不提供访问子节点所需的 API，而是提供其 forks< 之一/a> 有更改。

[aTFHppleElement Children] 提供对子节点数组的访问。它是一个 TFHppleElement 数组。查看 HTML 结构，只有少数有子节点，因此，

for (int i=0;i<[busNumbs count];i++) {
    TFHppleElement *busNumb = [busNumbs objectAtIndex:i];
    NSString *out = [busNumb content];
    if ( [[busNumb children] count] != 0 ) {
        out = [out stringByAppendingFormat:@" %@", [[busNumb firstChild] content]];
    }
    NSLog(@"%@",out);
}

The <font> tag is a child node to the anchor tag. The description [aTFHppleElement content] is incorrectly described as the innerHTML as it only contains the textual content of the element and not the content of its child nodes. So you will need to access the child nodes to display that information. As it were, the code in the repository doesn't provide the neccessary API to access the child nodes but one of its forks has the changes.

[aTFHppleElement children] provides access to the array of child nodes. It is an array of TFHppleElement's. Looking at the HTML structure, only few of them have the child nodes so,

for (int i=0;i<[busNumbs count];i++) {
    TFHppleElement *busNumb = [busNumbs objectAtIndex:i];
    NSString *out = [busNumb content];
    if ( [[busNumb children] count] != 0 ) {
        out = [out stringByAppendingFormat:@" %@", [[busNumb firstChild] content]];
    }
    NSLog(@"%@",out);
}
