Solutions to Bugs and Preview of Next Month's Part 2

Solutions to Bugs

There were four errors in Examples/collection1bugs.xml, all of which are reported clearly by IE5:

1. The processing instruction attribute standalone only accepts "yes" and "no", not "YES", since XML is case sensitive.
2. Attribute values must always be quoted, even if numeric: Peak weeks=4 should be Peak weeks="4"
3. Because XML is case sensitive, <Author> and </author> refer to different elements.
4. There is a missing end tag: </Notes>

There were three errors in Examples/collection1pubbugs.xml with respect to the Examples/collection1.dtd. If you're using IE5b2 or a validating parser, they will be reported. If you're using IE5 (March 18, 1999), these errors won't be reported.

1. The Value element is not defined in the DTD, so it is not valid.
2. The attribute Publisher within the Published element should be publisher (lowercase), as per the DTD.
3. Although Notes is a valid element within a Book, it is not valid for a CD, according to the DTD.

Note that none of these three errors are related to well-formedness; they all result from validating against the DTD. While IE5 does not report such errors, it will report syntax errors in the DTD itself, as we can see from Examples/collection1bugsdtd.xml:

	Invalid character found in DTD. Line 8, Position 1 

	This line should be flagged as illegal in the DTD.
