Hi,

Is it possible to have a drop-down menu, or something similar to it in XML Schema? I have an element called paymentFrequency and there are basicly 7 different possible types. How can I get it so that a person creating an XML document using my schema will end up picking one of these values in the paymentFrequency element?

Thanks

<form name="Form1">
<select name="paymentFrequency">
<option value="" selected="selected">Select one</option>
<xsl:for-each select="/....">
<option value="{PaymentFrequency}">
<xsl:value-of select="PaymentFrequency"/>
</option>
</xsl:for-each>
</select>
</form>

Use the Enumeration facet to restrict the string type:

<xsd:simpleType name="paymentFrequencyType">
  <xsd:restriction base="xsd:string">
    <xsd:enumeration value="Here is one type"/>
    <xsd:enumeration value="Ok, this is good too."/>
    <xsd:enumeration value="Maybe you want this one?"/>
    <!-- and so on ... -->
  </xsd:restriction>
</xsd:simpleType>

Whether or not the application the person is using will provide a dropdown based on the schema is dependant on the editor itself.  Notepad, for example, doesn't care anything about schemas.  XML Spy, on the other hand, will examine the schema, and figure out what values are allowed in context.  When you create a new element of that type, XML Spy will show you a list of allowable values, for you to pick from.

Thanks for your reply, just wanted clear something up.
So are you saying that I restrict the value using an attribute within the element of paymentFrequency?

No, I'm saying the W3C XML Schema can restrict the value of paymentFrequency directly.  The Schema defines the content model for paymentFrequency.  There are a number of different ways to accomplish the same thing in Schema, and the above example showed one way, by defining a simpleType.  You then create your element declaration like:

<xs:element name = "paymentFrequency" type="user:paymentFrequencyType" />

I can only guess at the exact syntax, as it depends on how you've declared your namespace, and how you've constructed the schema.  So my example might not cut-and-paste into your schema, but it shows the approach.
