java - Nested html not being parsed by Jsoup -

I am trying to parse one page with JSOP, but the HTML is not correctly parsed.

The general structure is:

  & lt; Html & gt; & Lt; Top & gt; ... & lt; / Head & gt; & Lt; Frameset ... & gt; & Lt; Frame ... & gt; #document & lt; Html & gt; ... & lt; / Html & gt; & Lt; / Frame & gt; & Lt; / Frameset & gt; & Lt; / Html & gt;   
 When I parse the html and print it, then  document doc = jsoup.parse (html); System.out.println (doc.html ());  
 This external HTML (including #documents, but not frame or internal HTML) prints.  
 Do anyone know how to get internal HTML with JSOU, or should I consider using a different library? Thank you.  
 EDIT: Here I am parsing the site. I have a subscription; Do not know if anyone will tell you in this.  
  
 After authentication, it will take you into:  
 Edit 2:  
    
 Then I run:  
  document doctor = jesop.ps (html); Elements ames = doc.select ("frameset> frame: last-child"); // print (ames); Switch (elems.size ()) {case: break; Case 1: Doctor = Jsoup.connect (elems.first (). Attr ("src")). Get (); break; Default: Break; } System.out.println (doc.html ());   
 Persevered HTML (doc.html ()):  
  & lt; Html & gt; & Lt; Top & gt; & Lt; / Head & gt; & Lt; Body & gt; & Amp; IUML; & Amp; Raquo; & Amp; Iquest; #document Hello Hello again & lt; / Body & gt; & Lt; / Html & gt;   
 Then also  & lt; Frameset & gt;   
 Is not anyone looking for ideas?  
 
 
 
 Ways to Paste Nested HTML:  
  // Frameset Document Doc = Jesup. Connect ("Http://database.asahi.com/library/2/login/login.php") .get (); // login, password, etc. Set the frame URL to which you want to parse ... Note: I think that you want to parse the contents of the first frame elements elements = doc.select ("frameset & Gt; frame: first-child "); Switch (elts.size ()) {case 0: // no frame found ... break; Case 1: element frame alt = alts.fst (); Document frame doc = jsoup Connect (framelt.ttR ("src")) .get (); // Add frame dock node to doctor (FrameAlt # insert child) frameElt.insertChildren (0, frameDoc.childNodes ()); break; Default: // Strange Result ...} System.out.println (doc.html ());
