[EP-tech] Re: Creating new citation formats....

If the output of your export uses EPrints::Utils::tree_to_utf8 (text.pm does in 3.3.10), then you should (according to the documentation) be able to add an html line break, that will get converted to a newline:
>From ~/perl_lib/EPrints/Utils.pm:
"$string = EPrints::Utils::tree_to_utf8( $tree, $width, [$pre], [$whitespace_before], [$ignore_a] )

Convert a XML DOM tree to a utf-8 encoded string.
If $width is set then word-wrap at that many characters.
XHTML elements are removed with the following exceptions:
<br /> is converted to a newline.
<p>...</p> will have a blank line above and below.
<img /> will be replaced with the content of the alt attribute.
<hr /> will, if a width was specified, insert a line of dashes.
<a href="foo">bar</a> will be converted into "bar <foo>" unless ignore_a is set.
 - might just work!?

If I have an XML file thus:

<cite:citation xmlns:xhtml="http://www.w3.org/1999/xhtml"; 
xmlns:cite="http://eprints.org/ep3/citation"; >
       <print expr="$item.citation('default')" />
       <print expr="$item.url()"/>

and export the data as a text file, this is all one line

I'm suspecting #2 is the way forward
I'm also suspecting #3 is more challenging that you appreciate :)
