DOM ParseError object

XML DOM Parse Error Object

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

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

parseError Object

A parser-error may occur when you try to open an XML document.

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

Note: The parseError object does not belong to the W3C DOM standard!

File Error

In the following code, we will try to load a file that does not exist and display certain error attributes:

Instance

<html>
<body>

<script>
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.load("ksdjf.xml");

document.write("Error code: " + xmlDoc.parseError.errorCode);
document.write("<br>Error reason: " + xmlDoc.parseError.reason);
document.write("<br>Error line: " + xmlDoc.parseError.line);
</script>

</body>
</html>

XML Error

In the following code, we ask the parser to load a malformed XML document.

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

Example

<html>
<body>

<script>
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.load("note_error.xml");

document.write("Error code: " + xmlDoc.parseError.errorCode);
document.write("<br>Error reason: " + xmlDoc.parseError.reason);
document.write("<br>Error line: " + xmlDoc.parseError.line);
</script>
