Hi all,
Following a suggestion from Daniel, I`m posting my question to the xmllist.
Our application want to print parsing errors detected through RelaxNG into
syslog.
But the line number and file name are not given to the error callback. Any
idea how to make that information showed ? Here`s the code that we are using :
void cfg_parsingErrCB ( void * ptr,
const char * msg,
...)
{
...
}
// create a parser context
ctxt = xmlNewParserCtxt();
if (ctxt == NULL) {
UTL_ABORT1( CFG_ModuleId,
"*** Failed to a parser context" );
return;
}
// Create a context pointer on the validation file
relaxngContextPtr = xmlRelaxNGNewParserCtxt(validationFile);
if ( relaxngContextPtr == NULL )
{
UTL_ABORT( CFG_ModuleId,
"*** Failed to create a parser context upon validation file
%s", validationFile );
return;
}
xmlRelaxNGSetParserErrors ( relaxngContextPtr,
(xmlRelaxNGValidityErrorFunc)
cfg_parsingErrCB,
(xmlRelaxNGValidityWarningFunc)
cfg_parsingErrCB,
stderr);
// Set all Error callbacks for dealing with CLF logs
xmlSetGenericErrorFunc ( ctxt, (xmlGenericErrorFunc) cfg_parsingErrCB );
// Validation of the validation file :)
schema = xmlRelaxNGParse( relaxngContextPtr );
if ( schema == NULL ){
UTL_ABORT( CFG_ModuleId,
"*** Failed to validate the validation file %s",
validationFile );
return;
}
xmlRelaxNGFreeParserCtxt(relaxngContextPtr);
validSchema = xmlRelaxNGNewValidCtxt (schema);
if ( validSchema == NULL ){
UTL_ABORT( CFG_ModuleId,
"*** Failed to validate the validation file %s",
validationFile );
return;
}
xmlRelaxNGSetValidErrors ( validSchema,
(xmlRelaxNGValidityErrorFunc) cfg_parsingErrCB,
(xmlRelaxNGValidityWarningFunc) cfg_parsingErrCB,
stderr);
/* Read the configuration file */
doc = xmlCtxtReadFile(ctxt, configurationFile, NULL, 0);
if (doc == NULL) {
if (configurationFile == NULL) {
UTL_ABORT( CFG_ModuleId,
"*** Failed to parse configuration file %s. File does
not exist.",
DEFAULT_CONFIG_FILE_NAME );
return;
}
else {
UTL_ABORT( CFG_ModuleId,
"*** Failed to parse configuration file %s. Invalid file
contents.",
configurationFile );
return;
}
}
/* Compare configuration file with the schema */
if ( xmlRelaxNGValidateDoc ( validSchema, doc ) != 0 )
{
UTL_ABORT( CFG_ModuleId,
"*** Failed to parse configuration file %s. File didn't
respect validation file %s.",
configurationFile, validationFile );
return;
}else {
UTL_LOG1( UTL_LOG_DEBUG,
CFG_ModuleId,
"*** Configuration file parsed successfully ! " );
}

Hum, possible, mais ca depends peut etre
1/ de la version de libxml2
2/ du type de callback d'erreur demandees (structuree ou pas)
Le mieux c'est de demander sur la liste avec un peu plus de details

merci, de meme !
