Hi all:
I am working on a C# application that involves using XML schema file as databases for message definitions and XML file as databases for message data.
I was following the example I found:http://msdn.microsoft.com/en-us/library/system.xml.xmldatadocument.dataset%28v=VS.100%29.aspx
I wrote my own xsd and XML file. I used the
same approach in the example, read the xsd file and then load
the xml file. But I don't have any "Rows" created for my DataTable. I used debugger to step through my codes. When I am get my DataTable use xmlDataDocument.DataSet.Tables["
name of the table"], the Rows property of that tables is 0.
Does anybody know what might cause the DataSet tables not get populated after I loaded the xmlDataDocument with XML file?
Here is a fragment of XSD file:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="test"
targetNamespace="http://tempuri.org/test.xsd"
elementFormDefault="qualified"
xmlns="http://tempuri.org/test.xsd"
xmlns:mstns="http://tempuri.org/test.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
>
<xs:element name="reboot_msg">
<xs:complexType>
<xs:complexContent>
<xs:extension base="header_s">
<xs:sequence>
<xs:element name="que_name">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:minLength value="4"/>
<xs:maxLength value="8"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
<xs:element name="priority" type="xs:unsignedShort"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:element>
and here is a fragment of the XML file:
<?xml version="1.0" standalone="yes"?>
<test xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >
<reboot_msg>
<message_length>16</message_length>
<message_type>7</message_type>
<message_sequence>0</message_sequence>
<que_name>NONE</que_name>
<priority>5</priority>
</reboot_msg>
It could be the XML and XSD file I created missed something. Please help.
Thanks
