Thanks Jason,
but this is the section that is not working, and yes the redirect.txt file does exist.
assigning the relevance to a parameter, I get a parameter add failed.
parameter “SourceDownload”="{(it, following text of last “/” of it | it) of node values of attributes “href” of xpaths (“xmlns:xhtml=‘http://www.w3.org/1999/xhtml’”, “//xhtml:a[@class=‘mscom-link failoverLink’]” ) of xml document of file “C:\temp\DownloadODT\redirect.txt”}"
