Parser Errors

The parseError object can be used to extract error information from the Microsoft XML parser.

The parseError Object

If you try to open an XML document, the XML Parser might generate an error. By accessing the parseError object, the exact error code, the error text, and even the line that caused the error can be retrieved.

The parseError object is not a part of the W3C DOM standard.

File Error

With this code we can try to load a non existing file, and display some of its error properties:

var xmlDoc = new ActiveXObject("Microsoft.XMLDOM")

xmlDoc.async="false"

xmlDoc.load("ksdjf.xml")

document.write(" Error Code: ") document.write(xmlDoc.parseError.errorCode)

document.write(" Error Reason: ") document.write(xmlDoc.parseError.reason)

document.write(" Error Line: ") document.write(xmlDoc.parseError.line)

XML Error

With this code we let the parser load an XML document that is not well formed.

var xmlDoc = new ActiveXObject("Microsoft.XMLDOM")

xmlDoc.async="false" xmlDoc.load("note_error.xml") document.write(" Error Code: ") document.write(xmlDoc.parseError.errorCode)

document.write(" Error Reason: ") document.write(xmlDoc.parseError.reason)

document.write(" Error Line: ") document.write(xmlDoc.parseError.line)
