HHC3003: The HTML tag "tag name" has invalid characters appearing before the closing angle bracket: "entry"

Problem: While parsing an HTML tag, the compiler found a character that is not valid.

Result: The compiler may become confused about the rest of the tags in your document. If warnings or errors that don't make sense occur after this error, they are probably a result of this error.

Solution: Check for a stray < character in the HTML page—this is the most common cause of this error. If you are certain the character is valid, you will need to convert it into an HTML symbol to prevent the compiler from having problems with the tag. For example, if you want to place an opening angle bracket in the page, use the characters &lt; instead of the angle bracket symbol.
