I've got around 100 captures that I need to process and extract some http & XML data from into a text file. I'm having problems getting the command-line syntax to work. Can someone take a look at my syntax and let me know what I'm doing wrong?

 $ tethereal -r soaplogs_00001_2007011808084032.cap -R "(http.host eq "myhost.mydomain.com") || (xml.tag == "<rejectlogin xsi:type=\"xsd:int\">") -T text -V > soap-xml-log.txt

What you're doing wrong is using using double-quotes around the filter expression. The filter expression includes double-quotes, so the first double-quote within the expression is interpreted by the shell as an *ending* quote.

Try

tethereal -r soaplogs_00001_2007011808084032.cap -R '(http.host eq "myhost.mydomain.com") || (xml.tag == "<rejectlogin xsi:type=\"xsd:int\">")' -T text -V > soap-xml-log.txt
