Re: XMLValidatingReader misses errors

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Your XML has a couple of issues:

1. You can not have <Software> as the document root as it is not a global
element in the schema, ONLY global elements can serve as document roots, in
this case you can only use <SoftwareSchema> as the document root.

2. Your XML is missing the namespace declaration on the root. The elements
in your XML must belong to the target namespace of the schema in order to
validate.

For both of the issues above, the modified XML is here:

<SoftwareSchema xmlns="http://tempuri.org/SoftwareSchema.xsd";>
<Software >
<Action>xxx</Action>
<Organization></Organization>
<SubOrganization>DIOR</SubOrganization>
<SoftwareName>10</SoftwareName>
<Version>12</Version>
<Platform>12</Platform>
<ProductDescription></ProductDescription>
<ProductType></ProductType>
<Manufacturer>3</Manufacturer>
<DataSource></DataSource>
<Upgrades></Upgrades>
<Cost>0.0000</Cost>
<LicenseKey></LicenseKey>
<LicensePurchased>8</LicensePurchased>
<LicenseUsed>9</LicenseUsed>
<LicenseEmail1></LicenseEmail1>
<LicenseEmail2></LicenseEmail2>
<LicenseEmail3></LicenseEmail3>
<SWStart>1900-01-01T00:00:00</SWStart>
<SWExpire>1900-01-01T00:00:00</SWExpire>
<PhysicalMedia>
<MediaType>CompactFlash</MediaType>
<BarcodeNumber>44</BarcodeNumber>
<NumberOfDisks>44</NumberOfDisks>
<LicenseKey>44</LicenseKey>
<OfficeLocation>44</OfficeLocation>
<DataSource>44</DataSource>
</PhysicalMedia>
</Software>
</SoftwareSchema>


With this I get the following validation errors, which I think are what you
expect:

The 'http://tempuri.org/SoftwareSchema.xsd:Action' element has an invalid
value according to its data type. The element
'http://tempuri.org/SoftwareSchema.xsd:Software' has invalid child element
'http://tempuri.org/SoftwareSchema.xsd:SubOrganization'. Expected
'http://tempuri.org/SoftwareSchema.xsd:SubOrg'. The
'http://tempuri.org/SoftwareSchema.xsd:SubOrganization' element is not
declared. An error occurred at file:///C:/tempTest/temp/test.xml, (5, 2).
The 'http://tempuri.org/SoftwareSchema.xsd:SWStart' element has an invalid
value according to its data type.
'http://tempuri.org/SoftwareSchema.xsd:SWExpire' element has an invalid
value according to its data type.


Thanks,
