while a shell solution is on the way , here is an alternative, in Python

Code:
>>> import fileinput
>>> Bcontents = open("fileB").read() #fileB contents stored as string
>>> for lines in fileinput.FileInput("fileA",inplace=1): #inplace editing of fileA
... 	lines = lines.strip() #get rid of newlines
... 	if lines.startswith("xxxx"):
... 		lines = Bcontents
... 	print lines

In fileA:

bor bor bor
something something
something
bib bib bi

NAME
git-stripspace - Remove unnecessary whitespace SYNOPSIS
git stripspace [-s | --strip-comments] git stripspace [-c | --comment-lines] DESCRIPTION
Read text, such as commit messages, notes, tags and branch descriptions, from the standard input and clean it in the manner used by Git. With no arguments, this will: o remove trailing whitespace from all lines o collapse multiple consecutive empty lines into one empty line o remove empty lines from the beginning and end of the input o add a missing to the last line if necessary. In the case where the input consists entirely of whitespace characters, no output will be produced. NOTE: This is intended for cleaning metadata, prefer the --whitespace=fix mode of git-apply(1) for correcting whitespace of patches or files in the repository. OPTIONS
-s, --strip-comments Skip and remove all lines starting with comment character (default #). -c, --comment-lines Prepend comment character and blank to each line. Lines will automatically be terminated with a newline. On empty lines, only the comment character will be prepended. EXAMPLES
Given the following noisy input with $ indicating the end of a line: |A brief introduction $ | $ |$ |A new paragraph$ |# with a commented-out line $ |explaining lots of stuff.$ |$ |# An old paragraph, also commented-out. $ | $ |The end.$ | $ Use git stripspace with no arguments to obtain: |A brief introduction$ |$ |A new paragraph$ |# with a commented-out line$ |explaining lots of stuff.$ |$ |# An old paragraph, also commented-out.$ |$ |The end.$ Use git stripspace --strip-comments to obtain: |A brief introduction$ |$ |A new paragraph$ |explaining lots of stuff.$ |$ |The end.$ GIT
