Top Forums UNIX for Dummies Questions & Answers Grep content in xml file Post 302870719 by Don Cragun on Monday 4th of November 2013 01:51:34 PM

If your 5MB xml file contains more than one line, I think vgersh99's script will produce more output than you want. If you are using a system where awk and sed have limited line lengths, both Yoda's script and vgersh99's script could fail if your xml file contains long lines.

The following awk script should get around these problems:
Code:
version=$(awk -F '=*"' '$1 == "SCHEMA_VERSION" { print $2; exit 0 }' RS=' ' file.xml)
printf "schema version is: %s\n" "$version"

If you want to run this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk.

With your sample input, the above script produces the output:
Code:
schema version is: 2.5

GOOGLE-SITEMAPGEN(1)					      General Commands Manual					      GOOGLE-SITEMAPGEN(1)

NAME

       google-sitemapgen -- simple script to automate production of sitemaps for a webserver

SYNOPSIS

       google-sitemapgen [--testing]  [--help]	[--config=config.xml]

DESCRIPTION

       This manual page documents briefly the google-sitemapgen command.

       This manual page was written for the Debian distribution because the original program does not have a manual page.

       google-sitemapgen  is  a  program that automatically produces sitemaps for a webserver, in the Google Sitemap Protocol (GSP). Sitemap files
       are XML listings of content you make available on your web server. The files can be directly submitted to search engines as hints  for  the
       search  engine  web  crawlers as they index your web site. This can result in better coverage of your web content in search engine indices,
       and less of your bandwidth spent doing it.

OPTIONS

       --config=config.xml
		 Specify the location of the configuration config.xml

       --testing Used to test the sitemap generator configuration.

       --help	 Display a summary of options and exit.

SEE ALSO

       /usr/share/doc/google-sitemapgen/examples/example_config.xml.gz
