Hi all,
I have a problem with xml that output from application I need to
validate one of the values by using XSD schema
The xml output like this

<?xml version="1.0" encoding="UTF-8"?>
<csv:csv xmlns:csv="http://xmlns.myapplication.com/2007/message-format/
csv"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.myapplication.com/2007/
message-format/csv right.xsd" >
<csv:line>
<csv:field>I</csv:field>
<csv:field>3871</csv:field>
<csv:field>0</csv:field> "i want to check this value"
<csv:field>25042008</csv:field>
<csv:field>0</csv:field>
<csv:field>4233</csv:field>
</csv:line>
<csv:line>
<csv:field>I</csv:field>
<csv:field>3871</csv:field>
<csv:field>29042008</csv:field>
<csv:field>25042008</csv:field>
<csv:field>6600183376</csv:field>
<csv:field>4233</csv:field>
<csv:field/>
</csv:line>
<csv:line>
<csv:field>I</csv:field>
<csv:field>3871</csv:field>
<csv:field>29042008</csv:field>
<csv:field>25042008</csv:field>
</csv:line>
</csv:csv>

I get the XSD schema like this

<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:csv="http://xmlns.myapplication.com/2007/message-
format/csv" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
attributeFormDefault="unqualified"
elementFormDefault="qualified" targetNamespace="http://
xmlns.myapplication.com/2007/message-format/csv"
xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:element name="csv">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" name="line">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" name="field"
type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

But the problem that I want to check the value of the third tag
<csv:field> to know if it contain 0 or 1
Can anyone help me on this

You would need to change your schema substantially to use e.g.
<xs:element name="field3">
<xs:simpleType>
<xs:restriction base="xs:int">
<xs:maxInclusive value="1"/>
<xs:minInclusive value="0"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
That is only possible if you choose different element names and types
for the fields, that is not possible with one field element of type
xs:string.

Thanks Martin for your reply
But the problem that the xml doesn’t contain fields names as you see
so I do not have element name “field3" so if you have any idea to get
the third element it will be helpful

If you want to use the XSD schema language then you will need to change
the schema you have and the XML you have.
As an alternative you could use a language like Schematron to formulate
the condition you have: http://www.schematron.com/
