Using VI "Load XML File", why does regular expression "1|2|4|8|16|32|64|128|256" not match "256" ?

[JaysonFix]

In my XSD file, I have:

	<xs:attribute name="bufferSize">
		<xs:simpleType>
			<xs:restriction base="xs:unsignedInt">
				<xs:pattern value="1|2|4|8|16|32|64|128|256"/>
			</xs:restriction>
		</xs:simpleType>
	</xs:attribute>

In my XML file, I have:

	<myElement bufferSize="256"/>

However, when I invoke VI "Load XML File", I find the following parse errors:

   Message: Datatype error: Type:InvalidDatatypeValueException, Message:Value '256' does not match regular expression facet '1|2|4|8|16|32|64|128|256'.

I have also tried:

<xs:pattern value="(1)|(2)|(4)|(8)|(16)|(32)|(64)|(128)|(256)"/>

I think instead of quotes you should use square braces:

[1|2|4|8|16|32|64|128|256]

Though I'm not too familiar with XML, that is how you would do it with LabVIEW

I'm not hip to XML, but I know that your expression will match the 2 in 256 before it matches what you're looking for.  You'll need to reverse the order of your regular expression.

Thats a good catch.

Of course Jim would jump all over a regex question
