What XSD format is this

I have the following type

  <xs:simpleType name="MoneyType">

    <xs:restriction base="xs:string">

      <xs:pattern value="\p{Nd}+(\.\p{Nd}\p{Nd})" />

    </xs:restriction>

  </xs:simpleType>

Open in new window


I use this for numeric fields

When I try to aggregate a large number of fields into a field with this structure, ti fails

Is there a better specification?

Thanks

Try this for currency

<xsd:simpleType name="money">
      <xsd:restriction base="xsd:decimal">
         <xsd:fractionDigits value="2"/>
      </xsd:restriction>
</xsd:simpleType>

The issue you might be having with the type you are using is the base type
<xs:restriction base="xs:string">
you should not use strings if your aim is to do calculations, use decimal instead.
Note that I posted a similar reply in an earlier question of yours
http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/XML/Q_28596088.html#a40547843
<xs:pattern value="\p{Nd}+(\.\p{Nd}\p{Nd})" />
is very similar to what I posted there
"\p{Nd}" is a regular expression indication for a decimal number... as is "\d",
consider the two equivalent, other than the base type
As I said in that other question, you would use the patern facet (one way to restrict the base type) if you need exactly 2 decimals as the fractional part

You are posting a number of questions, sometimes it is better to ask some extra information in an existing question, rather than starting yet another question that is hardly any different. We do give feedback even after you closed a question.
Try to really understand what we post before jumping to the next question... this forum will serve you as a better learning aid that way

Michael74's suggestion is not different from what I gave you in that other question
http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/XML/Q_28596088.html#a40547824
fractionDigits serves as a limitation, not as an exact number
so
99.99 is OK
99.9 is OK too
99.999 is not OK
If that is sufficient restriction for your purposes, I recommend that way
