RE: [xml-dev] can attribute in XML schema hold value and unit

["Sreeni Yetchina -X \(syetchin - Pure Solutions at Cisco\)" <syetchin@cisco.com>]

Step 1: Take this XSD Code fragment(This is email validation code fragment from another xsd file)

 

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

  <xsd:element name="Email" type="EmailType" />

  <xsd:simpleType name="EmailType" >
    <xsd:restriction base="xsd:token">
      <xsd:pattern value="([\.a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+(([a-zA-Z0-9_-])*\.([a-zA-Z0-9_-])+)+"/>
    </xsd:restriction>
  </xsd:simpleType>

</xsd:schema>

 

 

Step2: replace the regular expression in the above code by picking the suitable regular expression from the following link

http://regexlib.com/DisplayPatterns.aspx?cattabindex=4&categoryId=5

 

Step 3: If you want to test the above regular expression, use this page http://regexlib.com/RETester.aspx

 

Hope that this helps

Yes, but per my message below, how would you validate using regular expressions *only* that the date value is not (for example) February 30th?

If I can remember correctly, I implemented the regular expression validation of Dates(like Feb28 etc) in the schemas(around 3 years back). There are bunch of code examples across the web for this. So, we can do validate the dates or for a given set of values- enumerated data (like days of a week) etc in the Regular expressions.

 

The date format decides the validation regular expression expression(ex: Regular expression for dd-MMM-yyyy is diff from mm/dd/yyyy)

 

Thanks,

Regular expressions may work to some degree in this case, but they won't provide the level of validation for units that you need. For example, a regular expression can be used to define the format for a date, but it cannot validate that a date of (for example) February 30 is not present, as it cannot validate the combination of month and year in this case.

 

So Len's example of an attribute for units, with an enumerated list of valid values, is the best approach.

Hi Mangesh,

You can have this in Schema.

Define simple type attribute and have a regular expression as the constraint on that simple type attribute according to your data+units combination.

Hi All,

 

I am creating a xml schema where I have to making a ‘attribute’ but can a attribute hold a value and unit.

My example is FlowRate, let’s the value and unit could be 100 GPM.

Can I have just one attribute for 100 and GPM both. Some times it might be 80 cFPS.

 

So can a attribute hold both or do I need element here.

 

Thanks,

 

Mangesh
