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.
