XSD mandatory element

[Chris West]

I have an schema that defines an element as mandatory, but I also want the
XML instance to have some content for that mandatory element.

I can use a regular expression to guarantee content, but I'm interested to
know if there is another way to achieve this (an attribute setting perhaps)?

Thanks

are you saying that the instance has to have some mandatory text content?

if so look at a minLength restriction on the element type in the schema e.g.

<xsd:simpleType name="PopulatedStringType">
<xsd:restriction base="xsd:string">
<xsd:minLength value="1"/>
</xsd:restriction>
</xsd:simpleType>

but remember that an element using this type would allow <mandatory>
</mandatory>
you could further restrict the string with a pattern to say that the content
must not be all white space
