Another sed solution with the loop technique, written as a multi-liner
Code:
sed -n '
  \#<OfferDefinition Id# {
    :Loop
    N
    \#</OfferDefinition># !b Loop
    \#<Type>Timer</Type>.*<EnableAtProvisioning>0</EnableAtProvisioning># p
  }
' file

I have used \#...# rather than the usual /.../ so I do not need ugly \/ escapes in the search string.
Another variant (with default printing if not deleted)
Code:
sed '
  \#<OfferDefinition Id# !d
  :Loop
  N
  \#</OfferDefinition># !b Loop
  \#<Type>Timer</Type># !d
  \#<EnableAtProvisioning>0</EnableAtProvisioning># !d
' file

lorder

LORDER(1)						      General Commands Manual							 LORDER(1)

NAME

       lorder - find ordering relation for an object library

SYNOPSIS

       lorder file ...

DESCRIPTION

       The input is one or more object or library archive (see ar(1)) files.  The standard output is a list of pairs of object file names, meaning
       that the first file of the pair refers to external identifiers defined in the second.  The output may be processed by tsort(1) to  find	an
       ordering of a library suitable for one-pass access by ld(1).

       This brash one-liner intends to build a new library from existing `.o' files.

	      ar cr library `lorder *.o | tsort`

       The need for lorder may be vitiated by use of ranlib(1), which converts an ordered archive into a randomly accessed library.

FILES

       *symref, *symdef
       nm(1), sed(1), sort(1), join(1)

SEE ALSO

       tsort(1), ld(1), ar(1), ranlib(1)

BUGS

       The names of object files, in and out of libraries, must end with `.o'; nonsense results otherwise.
