Replacing variable Text between fixed strings

Replacing variable Text between fixed strings
Hello all,
This is my first post and I hope you can help me out.
I searched for quite some hours now and haven't found a simple solution to my problem.
It is as following:
I got this file:
dl.dropbox.com/u/14586156/stuff/Bookmarks.plist
and want to replace the Text between "file://localhost/ and /Documents/ with whatever. (Not literaly whatever, just any other text).
( in BASH/SHELL)
Since this is not a normal sorted text file and instead a plist it seems a quite
task to do.
I guess sed and gawk should be able to do this, yet neither of the solution provided anywhere helped me to accomplish this
I really hope anyone could help me with this since it is driving me crazy.
Thanks in advance for helping out a desperate shell scripting newb:
pasc
BTW: if there is a solution: Can these replacements also be limited to the ocurrences (e.g. only replace the first, second or maybe third occurence ?
Also: Is there any plist parsing utility for shell or awk that can write the parsed result to a new file in easily readable format ?

PLUTIL(1) BSD General Commands Manual PLUTIL(1) NAME
plutil -- property list utility SYNOPSIS
plutil [command_option] [other_options] file ... DESCRIPTION
plutil can be used to check the syntax of property list files, or convert a plist file from one format to another. Specifying - as an input file reads from stdin. The first argument indicates the operation to perform, one of: -help Show the usage information for the command and exit. -p Print the property list in a human-readable fashion. The output format is not stable and not designed for machine parsing. The purpose of this command is to be able to easily read the contents of a plist file, no matter what format it is in. -lint Check the named property list files for syntax errors. This is the default command option if none is specified. -convert fmt Convert the named file to the indicated format and write back to the file system. If the file can't be loaded due to invalid syntax, the operation fails. fmt is one of: xml1, for version 1 of the XML plist format binary1, for version 1 of the binary plist format json, for the JSON format There are a few additional options: -- Specifies that all further arguments are file names -s Don't print anything on success. -r For JSON, add whitespace and indentation to make the output more human-readable. -o path Specify an alternate path name for the result of the -convert operation; this option is only useful with a single file to be converted. Specifying - as the path outputs to stdout. -e extension Specify an alternate extension for converted files, and the output file names are otherwise the same. DIAGNOSTICS
The plutil command exits 0 on success, and 1 on failure. SEE ALSO
