XML-Schema: Replace spaces

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.

eg: "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!

Answer 1

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.

Answer 2

您可以使用whiteSpace方面将多个空间折叠为一个空间（等同于XSLT的normalize-space（）函数，但不能删除所有空间）。
