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) ||
tidyNodeIsBASE(child) ||
tidyNodeIsBASEFONT(child) ||
tidyNodeIsCAPTION(child) ||
tidyNodeIsCOL(child) ||
tidyNodeIsCOLGROUP(child) ||
tidyNodeIsDD(child) ||
tidyNodeIsDIR(child) ||
tidyNodeIsDL(child) ||
tidyNodeIsEMBED(child) ||
tidyNodeIsEM(child) ||
tidyNodeIsFRAME(child) ||
tidyNodeIsFRAMESET(child) ||
tidyNodeIsIMG(child) ||
tidyNodeIsISINDEX(child) ||
tidyNodeIsLINK(child) ||
tidyNodeIsLAYER(child) ||
tidyNodeIsLISTING(child) ||
tidyNodeIsMAP(child) ||
tidyNodeIsMARQUEE(child) ||
tidyNodeIsMENU(child) ||
tidyNodeIsMETA(child) ||
tidyNodeIsNOBR(child) ||
tidyNodeIsNOFRAMES(child) ||
tidyNodeIsNOSCRIPT(child) ||
tidyNodeIsOBJECT(child) ||
tidyNodeIsOL(child) ||
tidyNodeIsOPTGROUP(child) ||
tidyNodeIsPARAM(child) ||
tidyNodeIsPRE(child) ||
tidyNodeIsProp(tdoc,child) ||
tidyNodeIsQ(child) ||
tidyNodeIsS(child) ||
tidyNodeIsSCRIPT(child) ||
tidyNodeIsSELECT(child) ||
tidyNodeIsSTYLE(child) ||
tidyNodeIsSPACER(child) ||
tidyNodeIsTABLE(child) ||
tidyNodeIsTR(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
