Question

I’m writing a XMl schema to check an xml file.
I want to add a restriction that checks, if the value contains spaces. If it does, they should be deleted.

e.g.: “Hello world” -> check -> “Helloworld”

If this isn’t possible, I would like to throw an error when a space is found. I tried it with but this only works if the value is “” or ” ” and not with “hello world”.

Thanks for your help!

You cannot replace characters, but a type does not accept spaces might bed declared like so:

<simpleType name="NoSpaceType">
    <restriction base="string">
        <pattern value="[^ ]+"/>
    </restriction>
</simpleType>

pattern is a regexp expression that you may change to better suite your needs.
