Validating Xml Namespace using XmlReaderSettings

EDN Admin · Mar 13, 2008

Hello,
Im having some trouble using the XmlReaderSettings in conjunction with an XmlValidatingReader when trying to validate the Xml namespace in an Xml document as part of a unit test.

I have an Xml document that looks something like the following (this is just a fragment, but it gets the point across):
 
<?xml version="1.0" encoding="utf-8" ?>
<Macros xmlns=<a title="http://schemas.modhul.com/BizTalk/Pipeline/Components http://schemas.modhul.com/BizTalk/Pipeline/Components http://schemas.modhul.com/BizTalk/Pipeline/Components >

<blockquote dir=ltr style="margin-right:0px

<Macro name="ActivityIdentity">
<blockquote dir=ltr style="margin-right:0px
<ContextProperty>ActivityIdentity</ContextProperty>
<ContextPropertyNamespace>schemas.microsoft.com</ContextPropertyNamespace> </blockquote>
</Macro> </blockquote>
<Macros

 <a title="http://schemas.modhul.com/BizTalk/Pipeline/Components/Archive http://schemas.modhul.com/BizTalk/Pipeline/Components/Archive 

XmlSchemaValidationException as expected. 

The validation code I am using is as follows (the code compiles fine and throws the exception when the structure is incorrect or I use an incorrect type (i.e. a character string in an int element)):
 
XmlReaderSettings xmlReaderSettings = new XmlReaderSettings();
xmlReaderSettings.ValidationType = ValidationType.Schema;
xmlReaderSettings.CheckCharacters = true;
xmlReaderSettings.IgnoreComments = true;
xmlReaderSettings.IgnoreProcessingInstructions = true;
xmlReaderSettings.IgnoreWhitespace = true;
xmlReaderSettings.Schemas.Add(<a title="http://schemas.modhul.com/BizTalk/Pipeline/Components/Archive http://schemas.modhul.com/BizTalk/Pipeline/Components/Archive http://schemas.modhul.com/BizTalk/Pipeline/Components/Archive , new XmlTextReader(Assembly.GetExecutingAssembly().GetManifestResourceStream(MACRO_DEFINITION_SCHEMA)));

using (XmlReader xmlValidatingReader = XmlReader.Create(new XmlTextReader(_XmlConfigFile), xmlReaderSettings))
{
<blockquote dir=ltr style="margin-right:0px
try 
{
<blockquote dir=ltr style="margin-right:0px
while (xmlValidatingReader.Read()) { } </blockquote>
}
catch (XmlSchemaValidationException)
{
<blockquote dir=ltr style="margin-right:0px
// Configuration file could not be validated against the XSD. 
EventLog.WriteEntry(EVENT_LOG_SOURCE, string.Format("The configuration file at {0} failed to validate. Please review the file and correct any defects.", _XmlConfigFile), EventLogEntryType.Error, (int)EventIds.ConfigurationFileValidation.XsdValidationError);
return (false); </blockquote>
}
catch (Exception)
{
<blockquote dir=ltr style="margin-right:0px
// A general error was encountered while validating the configuration file. 
EventLog.WriteEntry(EVENT_LOG_SOURCE, string.Format("The configuration file at {0} failed to validate. Please review the file and correct any defects.", _XmlConfigFile), EventLogEntryType.Error, (int)EventIds.ConfigurationFileValidation.GeneralXsdValidationError);
return (false); </blockquote>
} </blockquote>
}
