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.

htsearch

htsearch(1)						      General Commands Manual						       htsearch(1)

NAME

       htsearch - create document index and word database for the ht://Dig search engine

SYNOPSIS

       htsearch [options] [query_string]

DESCRIPTION

       Htsearch  is  used to sift through the  databases created by htdig for content.	It is the actual search engine of the htdig search system.
       It is a CGI program that is expected to be invoked by an HTML form. It will accept both the GET and POST methods of passing data to the CGI
       program.

OPTIONS

       query_string
	      A  CGI-style query string can be given as a single argument, and is only used if the REQUEST_METHOD environment variable is not set.
	      If no query_string is given, and REQUEST_METHOD is not set, htsearch will prompt for the query.

       -c configfile
	      Use the specified configfile instead of the default (for security reasons this option is only available when htsearch is used on the
	      command line).

       -v -d  Run  in  verbose	mode.	This increases the verbosity of the program.  Using more than 2 is probably only useful for debugging pur-
	      poses.  The default verbose mode gives a progress on what it is doing and where it is.

FILES

       /etc/htdig/htdig.conf
	      The default configuration file.

       /etc/htdig/header.html
	      The default search results header file

       /etc/htdig/footer.html
	      The default search results footer file

       /etc/htdig/wrapper.html
	      The default search results wrapper file, that contains the header and footer together in one file

       /etc/htdig/nomatch.html
	      The default 'no matches found' HTML file

       /etc/htdig/syntax.html
	      The default file that explains boolean expression syntax errors

SEE ALSO

       Please refer to the HTML pages (in the htdig-doc package)  /usr/share/doc/htdig-doc/html/index.html  and  the  manual  pages  htdig(1)  and
       htmerge(1) for a detailed description of ht://Dig and its commands.

AUTHOR

       This manual page was written by Stijn de Bekker and updated by Robert Ribnitz. It is based on the HTML documentation of ht://Dig.
