generating schema for a xml file

[jaango123]

Hi All,

I have been using eclipse and MS visual studio .net. I am looking for a way to generate a schema based on the input xml. Visual studio generated as shown below. However, is there a way to mention the below properties through GUI.
properties
<xs:whiteSpace value="collapse"></xs:whiteSpace>
<xs:maxLength value="16"></xs:maxLength>

xml

<dsureq>
    <request_id>DSUPROFILE4REQ</request_id>
    <control_data>12345</control_data>
    <plastic_number>1234567890</plastic_number>
    <cycle_date>Test</cycle_date>
    <echo_common>A</echo_common>
    <echo_reposition>0</echo_reposition>
    <correlation_id>Test</correlation_id>
</dsureq>

xsd using MS visual studio

<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="dsureq">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="request_id" type="xs:string" />
                <xs:element name="control_data" type="xs:unsignedShort" />
                <xs:element name="plastic_number" type="xs:unsignedInt" />
                <xs:element name="cycle_date" type="xs:string" />
                <xs:element name="echo_common" type="xs:string" />
                <xs:element name="echo_reposition" type="xs:unsignedByte" />
                <xs:element name="correlation_id" type="xs:string" />
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>
