Retrieving xml nodes from a custom config section with nested collect

Question

Hi,

 

I need help on retrieving element values of the following custom Section in the configuration .

<SecurityAttributeCustomMetadata>
<attribute displayName="Security : projectname">
<add collectionTypeName="BasicExperiment" sectionTypeName="Title" fieldName="Metadata" propertyName="ProjectName"/>
</attribute>
<attribute displayName="Security : projectNumber">
<add collectionTypeName="BasicExperiment" sectionTypeName="Title" fieldName="Metadata" propertyName="ProjectNumber"/>
</attribute>
<!-- Fields from two section type can be combined together and configure as a single security attribute in the SNB -->
<attribute displayName="Security : customName">
<add collectionTypeName="BasicExperiment" sectionTypeName="Title" fieldName="Metadata" propertyName="userName"/>
<add collectionTypeName="MyExperimentType" sectionTypeName="MySectionType" fieldName="MyFieldName" propertyName="MyPropertyName"/>
</attribute>

Please help.

Thanks
