Bodged using string functions :-)

set $data = ''.join([line for line in ($seq_source_type.seq_paste.split()) if 
line[0] != ">"])

Removes the fasta header line and any white-space so I can pipe sequence 
directly to blastn.
Means users can quickly paste in a bit of sequence for blasting without first 
having to upload the data to their history.

Hi Russell,

There may be a better way, but this works for me in the Toolfactory to create 
space and special character free names?

<param name="foo" type="text" value="" label="Foo">
<sanitizer invalid_char="">
 <valid initial="string.letters,string.digits"/>

I want to add a filter to strip whitespace and newlines from a text input box 
so I can pipe the sanitized string to a command.
Documentation is a bit sparse (and my Python a bit basic) so does anyone have 
an example?
Perhaps there's a better way of doing it - regex maybe?

Any ideas?
