XML by Example

Admittedly, the XML industry is not as large as the SQL industry, but it’s

catching up fast. By moving your data to XML rather than an esoteric syn-

tax, you can tap the growing XML industry for support.

Names in XML

Element names must follow certain rules. As we will see, there are other

names in XML that follow the same rules.

Names in XML must start with either a letter or the underscore character

(“_”). The rest of the name consists of letters, digits, the underscore charac-

ter, the dot (“.”), or a hyphen (“-”). Spaces are not allowed in names.

Finally, names cannot start with the string “xml”, which is reserved for the

XML specification itself. ...
