using sed to conditionally extract stanzas of a file based on a search string
Dear All,
I have a file with the syntax below (composed of several <log ..... </log> stanzas)
I need to search this file for a number e.g. 2348022225919, and if it is found in a stanza, copy the whole stanza/section (<log .... </log>) to another output file.

The numbers to search for are listed in an input file (easy enough to read that file in one line at a time), but I am having major problems trying to build a conditional instruction using sed to search the file (below) for a particular number and then copy its whole section if a match is found. Thanks.
