Parsing HTML <Tag> into ios - iphone

Question

i am Parsing HTML Tag into iOS using Hpple. i am able to parse the data where the HTML Tag is
<div id="NewsPageSubTitle">
<p><**span** hi how are you>
Using ios code:
NSString *tutorialsXpathQueryString = #"//div[#id='NewsPageArticle']/p/span ";
NSArray *tutorialsNodes = [tutorialsParser searchWithXPathQuery:tutorialsXpathQueryString];
but in few case i don't have span, imean the string in html is accessed by tag "p" directly like:
<div id="NewsPageSubTitle">
<p>< hi how are you>
Here I am using ios code as:
NSString *tutorialsXpathQueryString = #"//div[#id='NewsPageArticle']/p ";
NSArray *tutorialsNodes = [tutorialsParser searchWithXPathQuery:tutorialsXpathQueryString];
but here i am getting a blank data in response.
can any one let me know how to solve the problem?

Answer 1

Since sometimes the para tag has span and sometimes it does not, I would suggest trying to handle that by looping over the children
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"index" ofType:#"html"];
NSData * data = [NSData dataWithContentsOfFile:filePath];
TFHpple * tutorialsParser = [[TFHpple alloc] initWithHTMLData:data];
NSString *tutorialsXpathQueryString = #"//div[#id='NewsPageSubTitle']";
NSArray *tutorialsNodes = [tutorialsParser searchWithXPathQuery:tutorialsXpathQueryString];
for (TFHppleElement * element in tutorialsNodes) {
NSLog(#"%#", element);
NSLog(#"%#", [element tagName]);
NSLog(#"%#", [element attributes]);
NSLog(#"%#", [element children]);
for (TFHppleElement *childElement in [element children]) {
NSLog(#"%#", childElement);
}
}

NSString *filePath = [[NSBundle mainBundle] pathForResource:#"image" ofType:#"html" inDirectory:#"New Folder 2"];
NSData * data = [NSData dataWithContentsOfFile:filePath];
NSFileHandle *readHandle = [NSFileHandle fileHandleForReadingAtPath:filePath];
NSString *htmlString = [[NSString alloc] initWithData:[readHandle readDataToEndOfFile] encoding:NSUTF8StringEncoding];
TFHpple * Parser = [[TFHpple alloc] initWithHTMLData:data];
NSString *query = #"//p";
NSArray *nodes = [Parser searchWithXPathQuery:query];
for (TFHppleElement *item in nodes)
{
NSLog(#"Title : %#", item.content);
NSLog(#"URL : %#", [item.attributes valueForKey:#"href"]);
}
