Thanks so much for the help Arnaud it compiled perfectly, but when I ran it said:

avinjoy@localhost:~/workspace/tidyPrueba$ g++ -g -Wall -I/usr/local/include main.cpp -L/usr/local/lib -ltidy -oparser
avinjoy@localhost:~/workspace/tidyPrueba$ ./parser
./parser: symbol lookup error: ./parser: undefined symbol: tidyNodeGetValue

It would seem that all the other functions are define (I tried with tidyNodeGetText and it worked fine) but not this one.

/usr/local/lib is the directory where the tidylib is installed using gnuauto.
The code I'm using is basically the same as the example in the web page with a few things modified:


void dumpNode( TidyNode tnod, int indent, TidyDoc tdoc ,TidyBuffer *output )
{
  TidyNode child;
  Bool interesa;

  for ( child = tidyGetChild(tnod); child; child = tidyGetNext(child) )
  {
    ctmbstr name;
    switch ( tidyNodeGetType(child) )
    {
        case TidyNode_Root:       name = "Root";                    break;
        case TidyNode_DocType:    name = "DOCTYPE";                 break;
        case TidyNode_ProcIns:    name = "Processing Instruction";  break;
        case TidyNode_Text:       name = "Text";                    break;
        case TidyNode_CDATA:      name = "CDATA";                   break;
        case TidyNode_Section:    name = "XML Section";             break;
        case TidyNode_Asp:        name = "ASP";                     break;
        case TidyNode_Jste:       name = "JSTE";                    break;
        case TidyNode_Php:        name = "PHP";                     break;
        case TidyNode_XmlDecl:    name = "XML Declaration";         break;

        case TidyNode_Start:
        case TidyNode_End:
        case TidyNode_StartEnd:
        default:
        {
             if ((tidyNodeGetType(child) == TidyNode_Comment) ||
                  tidyNodeIsADDRESS(child)  ||
                  tidyNodeIsAPPLET(child)   ||

                  tidyNodeIsWBR(child)      ||
                  tidyNodeIsXMP(child)
                )
             {
                 tidyBufClear(output);
                 continue;
             }
             else{
                 //name = tidyNodeGetName( child );
                 interesa=(Bool)1;
             }
        }
    }
    if (interesa)
    {
        //assert( name != NULL );
        //printf( "\%*.*sNode: \%s\n", indent, indent, " ", name );
        tidyBufClear(output);
        tidyNodeGetValue(tdoc,child,output);
        std::cout << "Value: " << output->bp <<std::endl;
    }
    dumpNode( child, indent + 4,tdoc, output);
  }
}

void dumpBody( TidyDoc tdoc, TidyBuffer *output )
{
  dumpNode( tidyGetBody(tdoc), 0, tdoc, output );
}

An this fucntion gets called from the main function in the same file

TidyBuffer output;
    TidyBuffer errbuf;
    int rc = -1;
    Bool ok;

    tidyBufInit(&output);
    tidyBufInit(&errbuf);

    TidyDoc tdoc = tidyCreate();
    ok = tidyOptSetBool( tdoc, TidyXhtmlOut, yes );  // Convert to XHTML
    if ( ok )
      rc = tidySetErrorBuffer( tdoc, &errbuf );      // Capture diagnostics
    if ( rc >= 0 )
      rc = tidyParseFile(tdoc, "ejemplo.htm");     // Parse the input
    if ( rc >= 0 )
     rc = tidyCleanAndRepair( tdoc );               // Tidy it up!
    if ( rc >= 0 )
      //rc = tidyRunDiagnostics( tdoc );
      dumpBody(tdoc, &output);

    tidyBufFree(&output);
    tidyBufFree(&errbuf);
    tidyRelease(tdoc);
    return rc;
}

Could it be a bug in the installation?

Thanks so much, in advance
Alejo

Use:
g++ -g -Wall -I/usr/local/include main.cpp -L/path/to/tidy/lib -ltidy
