I'm downloading a 10MB zipped XML file with wget, unzipping it to 40MB, trying to weed out test and expired entries (if the text of a certain node is "This is a test opportunity. Please DO NOT apply!" or if is in the past), and then convert to CSV.
However, I get this error:
PHP Notice: Array to string conversion in /home/morris/projects/grantsgov/xml2csv.php on line 46
I get Array errors because some entries in the XML file have more than one occurrence of a node (different text contents). The test entries are still present.

How can I fix the error and remove expired entries (based on ArchiveDate)? I suspect the second to last line in feddata.xsl needs to be fixed.
