     I am looking for the syntax to capture XML tags marked with 
/DescriptorName MajorTopicYN="Y"/ , but the combination of the internal 
space (between "Name" and "Major" and the embedded quote marks are 
defeating me. I can get all the "DescriptorName" tags, but these include 
both MajroTopicYN = "Y" and "N" variants. Any suggestions?

Thanks in advance.
