특정 div의 xpath 찾기

웹 페이지에서 특정 div의 컨텐츠를 가져 오기 위해 hipple 라이브러리를 사용하고 있습니다.특정 div의 xpath 찾기

사용법 : 이제

NSData* data = [trimmedString dataUsingEncoding:NSUTF8StringEncoding]; 

TFHpple *xpathParser = [[TFHpple alloc] initWithHTMLData:data]; 
NSArray *elements = [xpathParser searchWithXPathQuery:@"//div[@id='container']"]; 
TFHppleElement *element = [elements objectAtIndex:0]; 
NSString *string = [element content]; 
NSLog(string);

내가 그 사업부 컨테이너의 내용에 문자열 * 문자열을 작성해야 생각 해요?

는이 오류와 충돌을 받고 있어요 :

* 인해 캐치되지 않는 예외 'NSRangeException'응용 프로그램 종료, 이유는 : '* - [__ NSArrayM objectAtIndex :] : 빈 배열 범위를 넘는 인덱스 0 '

이제는 해당 div의 배열이 채워지지 않았기 때문입니다. 그 이유 중 하나는 그것이 내가 준 링크를 파싱하지 못했지만 xpath 파서에 추락하지 않았기 때문에 그 파스텔을 잘 추측 할 수 있을까요? 잘못이 줄을 나에게 그 내 XPath를 알려줍니다

이

searchWithXPathQuery:@"//div[@id='content']"];

사람이 나 텍스트 "나는 아래의 모든 텍스트가 필요합니다 :"아래의 DIV에 대한 XPath를 찾을 수 있습니다 (내가 제공 한 위의 모든 div의는

    I need all this text below: 

    <div class="content"> 
    <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even" property="content:encoded"><p>Data centre security is a big issue – especially for co-location centres hosting multiple racks for multiple, often competing, clients. Yet whilst security to access the data centre can often be impressive, individual rack level security is often inadequate. Given the number of in-house staff and external engineers, from cablers to storage and server providers, traipsing through a data centre on a near daily basis, poor rack level security is a potential risk.</p> 
<p>According to a recent survey conducted by Lieberman Software, 42 percent of IT staff can get unauthorised access to their organisation’s most sensitive information – including the CEO’s private documents. The failing is blamed on management’s naivety when it comes to understanding just how much privileged access their IT departments actually have.</p> 
<p>The fact that most racks are secured only with standard handles using a manual key, bears out this survey. Easily broken or bypassed, these locks provide minimal corporate protection; they offer no access control or audit trail of activity. Given the huge ongoing investment in data centres - during 2011-2012, the UK invested an estimated $3.35 billion in data centres; the second highest spending of any country, according to the Datacentre Dynamics Global Industry Census 2011 - extending standard access control techniques to the data centre racks is an important step.</p> 
<p>Companies can opt for a rack specific key, combination locks or key cards that are IP enabled to allow an organisation to impose strict control over the time/day an individual is allowed to access the rack. Using standard access control software, all activity is recorded and audited, providing the organisation with a complete list of those who have accessed the racks.</p> 
<p>For organisations, this approach adds control and addresses one important aspect of the internal threat. For co-location sites, rack level security removes the need to cage off client specific rack space areas freeing up space that can be used for more racks, delivering a return on investment, as well as improved client security.</p>

편집 (그것은 HTML의 페이지의 마지막 DIV이다). 전체 HTML을 기반으로, 나는 XPathQuery에게

변경 그런 다음

는 자식을 반복, 이것에 대한

-(NSString*) getStringForTFHppleElement:(TFHppleElement *)element { 

    NSMutableString *result = [NSMutableString new]; 

    // Iterate recursively through all children 
    for (TFHppleElement *child in [element children]) 
     [result appendString:[self getStringForTFHppleElement:child]]; 

    // Hpple creates a <text> node when it parses texts 
    if ([element.tagName isEqualToString:@"text"]) 
     [result appendString:element.content]; 

    return result;

감사를 텍스트를 얻을 수있는 페이지의 : 마지막 "내용"하지만 그 나는 HTML의 부하를 붙여 넣을 didnt는 나의 질문에 바로 마지막 . 네 번째 "content"클래스의 텍스트는 어떻게 얻을 수 있습니까? – dev6546

네 번째 div를 원한다면'element = [elements objectAtIndex : 3]' – nicolasthenoz

아아, objectAtIndex가 없어졌습니다. 감사합니다. – dev6546
