xmlReaderForFile Crashes when called recursivelly for different files.... Please need immediat

Hi,

 

I am using the libXML to my load xml file. I am using the windows version

of the libXML, which I downloaded from http://www.zlatkovic.com/libxml.en.html.

I call the same function recursively to load the parent and alias xml files. I call this function

when an event occurs on a thread. The program crashes when I call xmlReaderForFile

for an alias in the main xml file. I mean it loads the parent xml successfully having the same alias xml,

but when it loads the alias for the main xml file it crashes.. COULD SOMEONE PLEASE HELP ME..

 

Code Snippet

===========

 

void loadConfiguration(string urlStr)

{

xmlInitParser();

      xmlTextReaderPtr reader = NULL;

      // XML_PARSE_NOCDATA, docs say it merges CDATA into #text.

      reader = xmlReaderForFile(urlStr.c_str(), NULL, XML_PARSE_NOENT | XML_PARSE_NOCDATA);

      if (reader)

      {

        ;    int ret = xmlTextReaderRead(reader);

if (ret == 1)

      {

        ;          processNode(reader);

           ;       xmlChar* parentURI = getAttribute(reader, (xmlChar*)"parent");

           ; if (loadParentAlso &;& parentURI)

{

           ;             _parentConfigName = string((const char*)parentURI);

loadConfiguration(_parentConfigName));

           ; }

           ;       xmlChar* aliasURI = getAttribute(reader, (xmlChar*)"alias");

           ; if (loadParentAlso &;& parentURI)

{

           ;             _aliasName = string((const char*)parentURI);

loadConfiguration(_aliasName));

           ; }

 }

      }

 

      xmlFreeTextReader(reader);

}

 

void loadConfig(void *pData)

{

      loadConfiguration("sampleApp.xml");

}

 

int _tmain(int argc, _TCHAR* argv[])

{

      loadConfiguration("sampleApp.xml");

      _beginthread( loadConfig, 0, NULL );

getch();

      return 0;

}

 

 

Hi,

 

I have an xml file of the below format.

 

<!—some comment generated..&quot;  -->

<Node1&gt;data</Node1>

 

How do I detect if the file has a root node or not?

I mean how do I make the difference between the below xml file and the above xml file.

 

<!—some comment generated.."&nbsp; -->

<RootNode>

<Node1&gt;data</Node1>

</RootNode>

 

I need to know it before parsing the whole file,

as I need to avoid the root node when I load the xml file.

So if the file is in the first format then I get wrong results..

 

regards,
