# XML DOM Parse Error Object

« Previous
Next Chapter »

Microsoft's parseError object can be used to retrieve error information from the Microsoft XML parser.

To see how Firefox handles parser errors, check out the next page of this tutorial.

## The parseError Object

When trying to open an XML document, a parser-error may occur.

With the parseError object, you can retrieve the error code, the error text, the line that caused the error, and more.

Note: The parseError object is not a part of the W3C DOM standard!

## File Error

In the following code we will try to load a non-existing file, and display some of its error properties:

## Example

xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.load("ksdjf.xml");
document.write("Error code: " + xmlDoc.parseError.errorCode);
document.write("
Error reason: " + xmlDoc.parseError.reason);
document.write("
Error line: " + xmlDoc.parseError.line);
Try it yourself »

## XML Error

In the following code we let the parser load an XML document that is not well-formed.

(You can read more about well-formed and valid XML in our XML tutorial)

## Example

xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.load("note_error.xml");
document.write("Error code: " + xmlDoc.parseError.errorCode);
document.write("
Error reason: " + xmlDoc.parseError.reason);
document.write("
Error line: " + xmlDoc.parseError.line);
Try it yourself »

Look at the XML file: note_error.xml

## The parseError Object's Properties

Property | Description

errorCode | Returns a long integer error code
reason | Returns a string containing the reason for the error
line | Returns a long integer representing the line number for the error
linepos | Returns a long integer representing the line position for the error
