SED on cygwin not working with Hex or Octal

Hi, I have downloaded a web page that I need to cleanup before passing to xmlstarlet.

Using UltraEdit's HEX utility part of my download is as follows:

3C 2F 61 3E 0A 09 0A 09 09 3C 2F 61 3E

which in ASCII is

Code:
</a>
	
		</a>

I need to locate this string and replace it with just </a>

I have tried:

Code:
awk '{ gsub(/\x0A\x09\x0A\x09\x09/, "<\/a>"); print}' in > out

Code:
sed -e 's/<\/a>\\n\\t\\n\\t\\t<\/a>/<\/a>/g' in > out

Code:
 sed -e 's/<\/a>\x0A\x09\x0A\x09\x09<\/a>/<\/a>/' in > out

Code:
sed -e  's/<\/a>\o012\o011\o012\o011\o011<\/a>/<\/a>/' in > out

but it is not having any of it - it just creates an identical output file.

I did create a test file with just two new lines in it and try "sedding" those but with no success. It is almost like my sed will not recognise anything other than plain text.

I am using sed GNU version 4.2.1 which, according to the documentation, happily supports such activities.

Any ideas folks?
