META tag   

Hi,
  
   How do I get directly META tag from IHTMLDocument2 interface?
   I am getting through get_all() function. Is it right way?

   Is there any other good technique?

Thanks in advance.

Regards,
siri.

document.all.tags("meta")

With sufficient thrust, pigs fly just fine. However, this is not 
necessarily a good idea. It is hard to be sure where they are going to 
land, and it could be dangerous sitting under them as they fly 
overhead. -- RFC 1925

Re: META tag   

Hi Igor,

   I am always getting "failed at tags" from the below function.

   Please correct me.
 
Code:

HRESULT CMyCls::HrGetMATATag(IHTMLDocument2 **pMSGHTML,BSTR &bstrMATA)
{
	IHTMLElementCollection* pListOfElements = NULL;
	HRESULT hr = NOERROR;
	hr = (*pMSGHTML)->get_all(&pListOfElements);

	FILE* FP = fopen("C:\\Tracefile.txt","a+");

	if (SUCCEEDED(hr))
	{
		CComVariant varMATA("MATA");

		IDispatch* pDispMATA = NULL;
		hr = pListOfElements->tags(varMATA,&pDispMATA);
		if (SUCCEEDED(hr))
		{
			IHTMLElement* pCONTENT = NULL;

			hr = pDispMATA->QueryInterface(IID_IHTMLElement,(void**)&pCONTENT);
			if (SUCCEEDED(hr))
			{
				BSTR bstrCHARSET;
				hr = pCONTENT->get_innerText(&bstrCHARSET);
				FILE* fp = fopen("C:\\chaset.txt","a+");
				USES_CONVERSION;
				fprintf(fp,"%s\n",W2A(bstrCHARSET));
				fclose(fp);
				if (FAILED(hr))	hr = E_FAIL;

				SysFreeString(bstrCHARSET);
				pCONTENT->Release();
			}
			else
				fprintf(FP,"%s\n","failed at tags");
			pDispMATA->Release();

		}
		else
			fprintf(FP,"%s\n","failed at tags");

		varMATA.Clear();
		pListOfElements->Release();
	}
	else 
		fprintf(FP,"%s\n","failed at get_all");

	fclose(FP);

	return hr;

}


Thanks in advance.

Regards,
Durga.

The tag name is META, not MATA.

tags() method returns a collection, not a single tag - there may be 
multiple meta tags. You should query for IHTMLElementCollection.
