The use of learning--hpple for third-party libraries developed by iOS

Because HTML parsing is likely to be encountered in development, HTML parsing tools are required if the data provided in the background is only HTML data, or if the app needs to get the data from the HTML in the front of the web.

About the HTML parsing library, you can read: Collect several objective-c HTML parsing libraries to understand. The following is my study of open source project coding encountered the use of hpple parsing tools, so take it out to learn and summarize.

Create a new normal project, and then I use POD integration with this hpple library to use:

Then I'm tired parsing parsing index.html files:

The main code:

1- (void) Touchesbegan: (Nsset<uitouch *> *) touches withevent: (Uievent *)Event{2NSData * data = [NSData datawithcontentsoffile:@"/users/heyang/documents/xcode/object-c/third-party library hpple Learning/hppletest/hppletest/index.html"];3NSLog (@"Data:%@", data);4Tfhpple * doc =[[Tfhpple alloc] initwithhtmldata:data];5     6Nsarray * elements = [doc searchwithxpathquery:@"//a"];7     8NSLog (@"number of a nodes:%ld", elements.count);9      for(inti =0; i < Elements.count; i++) {TenTfhppleelement * E =[elements objectatindex:i]; OneNSLog (@"1:%@", [e text]);//The text inside the HTML element (the content of the first text node) ANSLog (@"2:%@", [e TagName]);//"a" -NSLog (@"3:%@", [e attributes]);//nsdictionary of HREF, class, ID, etc. -NSLog (@"4:%@", [E Objectforkey:@"href"]);//Easy access to single attribute theNSLog (@"5:%@", [E Firstchildwithtagname:@"img"]);//the first "B" Child node -NSLog (@"=========== parsing completed once ==========="); -     } -}

The printing results are:
