Java Parsing XML using shell script
Well, issue is i have to parse this script to get the VERSION:

Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>CFBundleAllowMixedLocalizations</key>
    <true/>
    <key>CFBundleDevelopmentRegion</key>
    <string>English</string>
    <key>CFBundleExecutable</key>
    <string>Adobe AIR</string>
    <key>CFBundleIconFile</key>
    <string>Adobe AIR</string>
    <key>CFBundleIdentifier</key>
    <string>com.adobe.AIR</string>
    <key>CFBundleInfoDictionaryVersion</key>
    <string>6.0</string>
    <key>CFBundlePackageType</key>
    <string>FMWK</string>
    <key>CFBundleVersion</key>
    <string>3.1.0.4880</string>
    <key>NSHumanReadableCopyright</key>
    <string>Copyright © 2007-2011 Adobe Systems Inc.</string>
</dict>
</plist>

So i want shell script to read this entry only the version and perform an operation if the version number is less than the given number.

Thanks a lot in advance!!

Code:
variable_sto_store=`awk -F"[<>]" '/CFBundleVersion/ {getline;print $3;exit}' input.xml`
 
If you want to capture it outside.

To exactly retrieve the value from an XML file, you need to use an XML tool such as xmllint. It comes with Linux by default.
Code:
$ version=`xmllint --xpath '/plist/dict/key[text()="CFBundleVersion"]/following-sibling::string[position()=1]/text()' input.xml`

$ echo $version
3.1.0.4880
