regexp

[xbury.cs at clearstream.com]

Andu,

I ranted about this sometime ago but the phylosophy behind GREP in
MC is for one liners "only" I was told...

I had a similar problem when parsing control statements in a code translator
and later in my Script Editor for the indexing...

Best is to first find the start of the string and match it's ending string
 (with offset("endofstring",container,posoffirststring). Then you remove the
returns
and then you can use the GREP if you so wish...

Thats's the simple way...
Otherwisely, you could replace all returns with a double character and then
use GREP...
You replace your double character with returns before returning the text...

Last but not least, use the two forms above, identify your chunk, remove the
returns,
replace with matchChunk your string and continue scanning your html...

Hope it helps!
Xavier
