Static libs Libtidy on QT4 clean html/xml

**patrik08** · 27th May 2006, 12:39

I have build successful libtidy on qt4

Now how i cann translate this C++ sample to make

bool Clean_Code_utf8(QString incomming_file, QString output_file, QString config_file)

Have anibody experience on tidy? I understand tidy only from php....

Qt Code:

Switch view

#include <tidy.h>
#include <buffio.h>
#include <stdio.h>
#include <errno.h>
 
 
int main(int argc, char **argv )
{
  const char* input = "<title>Foo</title><p>Foo!";
  TidyBuffer output = {0};
  TidyBuffer errbuf = {0};
  int rc = -1;
  Bool ok;
 
  TidyDoc tdoc = tidyCreate();                     // Initialize "document"
  printf( "Tidying:\t%s\n", input );
 
  ok = tidyOptSetBool( tdoc, TidyXhtmlOut, yes );  // Convert to XHTML
  if ( ok )
    rc = tidySetErrorBuffer( tdoc, &errbuf );      // Capture diagnostics
  if ( rc >= 0 )
    rc = tidyParseString( tdoc, input );           // Parse the input
  if ( rc >= 0 )
    rc = tidyCleanAndRepair( tdoc );               // Tidy it up!
  if ( rc >= 0 )
    rc = tidyRunDiagnostics( tdoc );               // Kvetch
  if ( rc > 1 )                                    // If error, force output.
    rc = ( tidyOptSetBool(tdoc, TidyForceOutput, yes) ? rc : -1 );
  if ( rc >= 0 )
    rc = tidySaveBuffer( tdoc, &output );          // Pretty Print
 
  if ( rc >= 0 )
  {
    if ( rc > 0 )
      printf( "\nDiagnostics:\n\n%s", errbuf.bp );
    printf( "\nAnd here is the result:\n\n%s", output.bp );
  }
  else
    printf( "A severe error (%d) occurred.\n", rc );
 
  tidyBufFree( &output );
  tidyBufFree( &errbuf );
  tidyRelease( tdoc );
  return rc;
}

Fundamentally, assuming the code is working, you simply need to re-encapsulate it in a function, open the "incomming_file", bring it into a buffer and feed it to tidy. Then take the output buffer and write it out to the "output_file" specified in the second arg.

What's the "config_file" arg for? If it contains tidy configuration directives (projecting, here), you'll have to open that up, parse out the directives, and then set up a construct to set the directives found.

tidy config file... preference html or xml and so show-warnings: no ....

so i can parse html or xml utf8 or iso...

Tanks i try .... if a problem i post on c++ forum...

Exactly on the config file.

Make sure you also test for invalid configuration keys, so you can flag up error.

user not write config file....
Is a CMS - CRM ... and must have clean xml report to xslt's (pdfs) and clean xhtml to webpage...

But i think is possibel to make chekbox GUI to write a new config file...

Great that you got it working.

Just looking over the code, I don't see where the configfile is used. It doesn't look like you're processing the directives or making set calls, anywhere.

Maybe it's not necessary?

Oops - on re-examination, I see where it's getting submitted to the tidy object.
Never mind.

Carry on,

**patrik08** · 29th May 2006, 17:28

Yes ist not need .... default file ...
Each config have a default value ...

numeric-entities: yes ..... ecc...

If You chanche default value .... is possibel to write each line ... same as php....
but I wand to add & write my own tag 18 pieces.... xml / xslt and a list is long.... so i make a file....

default value i found here.... http://perens.com/Slides/Copenhagen0/tidy.conf
