Is XML case-sensitive?

Short question

Is XML case-sensitive?

Longer question

For example:

<Shirt color="Red"/>

The attribute color is of type string that may contain a set of valid colors (Red, Blue and Green).

To validate the XML, I used the following XSD:

  <xs:simpleType name="ColorType">
    <xs:restriction base="xs:string">
      <xs:enumeration value="Red"/>
      <xs:enumeration value="Blue"/>
      <xs:enumeration value="Green"/>
    </xs:restriction>
  </xs:simpleType>

Am I expected to accept different case variations of Red, Blue and Green? Or XML is widely accepted as case-sensitive?

Solution

  • Short Answer:

    Yes - XML is case sensitive.

    Longer Answer:

    It is widely accepted as case sensitive, however if you want to accept more flexibly, take a look at the question below, which discusses having case-insensitive enumerations:
