XSD Restriction based off of certain numbers in range using regular expression - regex

Question

I am working on creating an XSD for a web service that will take in an ID number as an element in the XML. These ID numbers consist of 10 consecutive digits ([0-9]{10}), but I was trying to create a regular expression that could exclude certain elements from this range.
For example, here is the restriction I have currently in my XSD:
<xsd:restriction base="xsd:string">
<xsd:pattern value="[0-9]{10}" />
</xsd:restriction>
I need the restriction to allow a string of [0-9]{10} that doesn't fit the following IDs:
All 0's: [0]{10}
Starting with 6: [6][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]
Starting with 000: [0][0][0][0-9][0-9][0-9][0-9][0-9][0-9][0-9]
Starting with 999: [9][9][9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]
Ends with 2 0's: [0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0][0]
4 0's in Middle: [0-9][0-9][0-9][0][0][0][0][0-9][0-9][0-9]
Is this possible to do from within the XSD or regular expression?
Thanks.

Answer 1

I'd rephrase your restrictions a bit:
The first digit must not be a 6.
At least one of the last two digits must not be a zero.
At least one of the middle four digits must not be a zero.
The first restriction, an ID only consisting of zeroes, is actually included in the two last restrictions.
The first restriction can be expressed by a set of allowed characters that does not include 6, i.e. [0-57-9].
For the other restrictions, a straightforward solution is to start at the beginning of a section that must not consist only of zeroes and assume a non-zero digit; if that assumption is true, the remaining digits may include zeroes; otherwise the first digit in that section must be a zero and for the remaining characters, this rule can be repeated recursively until only one character is left: ([1-9][0-9]{3}|0(... repeat for three digits, then two digits, ...))
Therefore, a suitable RegEx would be:
[0-57-9][0-9]{2}([1-9][0-9]{3}|0([1-9][0-9]{2}|0([1-9][0-9]|0[1-9])))[0-9]([1-9][0-9]|0[1-9])
Update: The additional restrictions require the following:
At least one of the first three digits must not be a 0.
At least one of the first three digits must not be a 9.
This can be included the same way as above, accepting either anything except 0 and 9, or either of these two numbers:
([1-57-8][0-9]{2}|0([1-9][0-9]|[0-9][1-9])|9([0-8][0-9]|[0-9][0-8]))([1-9][0-9]{3}|0([1-9][0-9]{2}|0([1-9][0-9]|0[1-9])))[0-9]([1-9][0-9]|0[1-9])
The new part is in the front of the expression:
([1-57-8][0-9]{2}|0([1-9][0-9]|[0-9][1-9])|9([0-8][0-9]|[0-9][0-8]))
So,
either the ID starts with neither a 0 nor with a 9. In that case, there are no restrictions for the next two digits.
or the ID starts with a 0. In that case, one of the next two digits must not be a zero, either the first one or the second one.
or the ID starts with a 9. In that case, one of the next two digits must not be a nine, either the first one or the second one.

Answer 2

I think this will cover it:
[01-57-9]\d{2}([1-9]\d{3}|\d[1-9]\d{2}|\d{2}[1-9]\d|\d{3}[1-9])\d([1-9]\d|\d[1-9])
Broken down:
[01-57-9] First character is a number-not-6.
\d{2} Next two characters can be any digit.
Then there is a (...|...|...|...) section, ORing all of these together.
[1-9]\d{3} Of the next 4 digits, the first cannot be zero.
OR
\d[1-9]\d{2} Of the next 4, the second cannot be zero.
OR
\d{2}[1-9]\d Or the third is not zero.
OR
\d{3}[1-9] Or the fourth is not zero.
Then we have another \d, any digit.
Finally,
([1-9]\d|\d[1-9]) either the first or the second of the last two digits cannot be 0.
Since we have two sections that demand at least one number is not zero, there is not way for all 10 to be zero.
