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.5.0");
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.DOMDocument50
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 "msxml5.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.5.0"));

      // 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();
}
