XML Validator
Use our XML validator to syntax-check your XML.
XML Errors Will Stop You
Errors in XML documents will stop your XML applications.
The W3C XML specification states that a program should stop
processing an XML document if it finds an error. The reason is that XML
software should be small, fast, and compatible.
HTML browsers will display documents with errors (like missing end tags). HTML browsers
are big
and incompatible because they have a lot of unnecessary code to deal with (and
display) HTML errors.
With XML, errors are not allowed.
Syntax-Check Your XML
To help you syntax-check your XML, we have created
an XML validator.
Paste your XML into the text area below, and syntax-check it by clicking the
"Validate" button.
Note: This only checks if your XML is "Well formed". If you want to
validate your XML against a DTD, see the last paragraph on this page.
Syntax-Check an XML File
You can syntax-check an XML file by typing the URL of the file into the
input field below, and then click the "Validate" button:
Note: If you get an "Access denied" error,
it's because your browser security does not allow file access across domains.
The file "note_error.xml" demonstrates your browsers error handling. If you want
see an error free message, substitute the "note_error.xml" with "cd_catalog.xml".
Validate Your XML Against a DTD
If you know DTD, you can validate your XML in the text area below.
Just add the DOCTYPE declaration to your XML and click the "Validate" button:
Note: Only Internet Explorer will actually check your XML against the
DTD. Firefox, Mozilla, Netscape, and Opera will not.
