IXMLDOMParseError

Example

The following script example attempts to load an XML document. It then tests the errorCode property of the IXMLDOMParseError object to see if an error has occurred.

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.4.0");
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode != 0) {
  alert("A parse error occurred.");
} else {
  alert(xmlDoc.documentElement.xml);
}

Example

The following Microsoft® Visual Basic® example attempts to load an XML document. It then tests the errorCode property of the IXMLDOMParseError object to see if an error has occurred.

Dim xmlDoc As New Msxml2.DOMDocument40
xmlDoc.async = False
xmlDoc.Load ("books.xml")
If xmlDoc.parseError.errorCode <> 0 Then
  MsgBox "A parse error occurred."
Else
  MsgBox xmlDoc.documentElement.xml
End If

Example

The following C/C++ example reads a document with a missing end "TITLE" tag (in the second book) and displays the error.

#import "msxml4.dll"
using namespace MSXML2;

inline void TESTHR( HRESULT _hr ) 
   { if FAILED(_hr) _com_issue_error(_hr); }

void XMLDOMParserSample()
{
   try
   {
      IXMLDOMDocumentPtr docPtr;

      //init
      TESTHR(CoInitialize(NULL)); 
      TESTHR(docPtr.CreateInstance("Msxml2.DOMDocument.4.0"));

      // load a document
      _variant_t varXml("D:\\xmlSample\\xmlTest\\book.xml");
      _variant_t varOut((bool)TRUE);
      varOut = docPtr->load(varXml);
      if ((bool)varOut == FALSE)
      {
         IXMLDOMParseErrorPtr errPtr = docPtr->GetparseError();
         _bstr_t bstrErr(errPtr->reason);

         printf("Error:\n");
         printf("Code = 0x%x\n", errPtr->errorCode);
         printf("Source = Line : %ld; Char : %ld\n", errPtr->line, errPtr->linepos);
         printf("Error Description = %s\n", (char*)bstrErr);
         
      }
      else
      {
         printf("Load successful");
      }

   }
   catch (_com_error &e)
   {
      printf("Error:\n");
      printf("Code = %08lx\n", e.Error());
      printf("Code meaning = %s\n", (char*) e.ErrorMessage());
      printf("Source = %s\n", (char*) e.Source());
      printf("Error Description = %s\n", (char*) e.Description());
   }
      catch(...)
   {
      printf("Unknown error!");
   }
   CoUninitialize();
}
