parsing - Advanced PDF parser for Java -

-

I want to remove content separately from a PDF file in Java:
  • Full viewer < / Li>
  • Image
  • Link

    Is it also possible to get the following?

    • Document Meta Tags
    • Title Only>
    • Documents like input elements

      Manipulate me or PDF does not need to render i files Which library would be most suitable for that kind of purpose?

      UPDATE

      Well, I tried Peedifboks of: 

        document luceneDocument = LucenePDFDocument.getDocument (new File (Path)); Field content = luceneDocument.getField ("content"); Println (contents.stringValue ());   
       But output is zero. Field "Summary" though okay.  
       The next snippet works fine.  
        PDDocument doc = PDDocument.load (path); PDFTextStripper Stripe = new PDFTextStripper (); String text = stripe.gettext (doctor); Println (text); Doc.close ();   
       But then, I have no clue how to remove images, links, etc.  
        UPDATE 2   
       I found an example of removing images, but how to remove I have not received any response yet:  < 
    •  
    •  Link  
    •  Document Meta Tags like Title, Description or Author < 
    •  Only Header  
    •  Input Element If there is a form in the document  Li>   
       
            It is difficult to parse all reciprocal text with sections of the com.itextpdf.text.pdf.parse package ... but those classes are not aware of clipping. You can easily force page size to be parsed.  
        // All text on the page, position of occurs regardless PdfTextExtractor.getTextFromPage (Reading, New page);   
       really need to override that takes a Tekstakstrkshn strategy, filtered strategy. it is interesting fairly quickly, but I think that whatever you want The week she can get "out of the box".  
       
         
      •  Image    
         Yes, through the same package classes. Image listeners are not supported as well as text listeners, but are present.  
         
           
        •  Link    
           Yes Links are "Annotations" for various PDF pages. Finding them is a simple thing of looping through the "annotation array" of each page and selecting link annotations.  
            pdfDictionary pagedict = myReader.getPageN (1); PDFAirotSotts = Pagedict.GetAsere (PDFNM.ANOTS); ArrayList & LT; String & gt; Dests = New Arrestist & lt; String & gt; (); If (annually! = Zero) {for (int i = 0; i   
           you can find.  
           
             
          •  input element    
             certainly Se.afafaa (Lie And Seekle Designer) or for old tech "accraform" forms, iText can find all the fields and their values.   Fields for myReader (string fldName: fieldNames) {System.out .println (fldName + ":" + fields.getField (fldName));}   does not have any informative information ... but it '       
             
               
             Previous>  Maps & lt; S tring, string & gt; Info = myPdfReader.getInfo (); System.out.println (notification); In addition to the original author / title / etc, there is a fairly complex XML schema that you can access through  reader.getMetadata () .    
               
            •  headlines only    
               A  text render filter  the criteria you want Depending on the text, you can ignore the text. Depending on your comment, the font size looks correct.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
