using XmlReader reader to extract an elemen in correlation with another element

Hi all
The xml file below has two different mimeType
in the Attachments node
1:  <mimeType>application/pdf</mimeType>
 2: <mimeType>application/pdf</mimeType>
I am looking for a way to get the value in content If and only if the value of mimeType
is "application/pdf"

Thanks in Advance


If (mimeType = "application/pdf")
    reader.ReadToFollowing("Content");
    varOutputString = (reader.ReadElementContentAsString());

using (XmlReader reader = XmlReader.Create(new StringReader(xmlString)))
{
    reader.ReadToFollowing("attachment");
    reader.MoveToFirstAttribute();
    string genre = reader.Value;
   
If (mimeType = "application/pdf")
    reader.ReadToFollowing("Content");
    varOutputString = (reader.ReadElementContentAsString());
}
