XSD: ways of restricting xml to non-empty tags?

[Piper707]

Hi,

I'd like to know if there are any more ways of restricting an XML
document to having only non-empty tags (containing Strings).

I can think of 2 ways:

1)

<xs:simpleType name="tagName">
<xs:restriction base="xs:string">
<xs:pattern value="([a-zA-Z0-9])+"/>
</xs:restriction>
</xs:simpleType>

2)

<xs:simpleType name="tagName">
<xs:restriction base="xs:string">
<xs:minLength value="1"/>
</xs:restriction>
</xs:simpleType>

But approach #2 would allow the user to get away with spaces between
the tags.

Are there any other ways of doing this?

Thanks
Rohit.

But [this] approach would allow the user to get away with spaces between
the tags.

use base="xs:token" instead, which implies aggressive whiteSpace
normalization.
