Sed bug in OS X?
I think I'm giving up on sed on OS X for now. I found a workaround with Perl (s/// works in Perl)

Next hurdle multi-line grep...

I find it really silly that multi-line grep is impossible using standard unix tools, but that's another matter

Here's a quick run down of what my small awk script does with each line of output from egrep:

awk -F">" '{print $2}'

splits

<photoshop:CaptionWriter>this is where the caption writer goes</photoshop:CaptionWriter>

into pieces using > as a field separator:

<photoshop:CaptionWriter
this is where the caption writer goes</photoshop:CaptionWriter

and grabs the second piece ($2), which is

this is where the caption writer goes</photoshop:CaptionWriter

Then the second awk command awk -F"<" '{print $1}' takes that line and splits it into pieces using < as a field separator:

this is where the caption writer goes
/photoshop:CaptionWriter

and grabs the first piece ($1), giving you:

this is where the caption writer goes

Cool!

With a slight modification to grab the field type out of the tag, this looks like it will work.

Thanks,

It's true! If you just sit at a keyboard and keep punching random keys, it is possible to come up with a solution! Smilie

<output from egrep command> | sed -e 's/<*[[/a-zA-Z0-9:]*]*>//g'

Great choice, using PERL. Many of us consider PERL a 'standard UNIX tool' , BTW. PERL is one of the finest pattern extraction languages in the known universe. SED and AWK are a bit 'dated' if you ask me (just my opinion). I'll take PERL and PHP any day.
