[TurboGears] Preserving newlines

[Cecil Westerhof]

I wanted to preserve newlines in the generated webpage. I had a
solution with split in my template. Something like:
#####
<element py:strip="" py:for="line in blogEntry.entryText.split('\n')">
    ${line}<br/>
</element>
#####

I made the following function:
#####
def splitLines(thisText):
    if thisText == None:
        return []
    thisText = thisText.replace('&', '&amp;')
    thisText = thisText.replace('<', '&lt;')
    thisText = thisText.replace('>', '&gt;')
    return '<br/>'.join(thisText.split('\n'))
#####

and now I can put the following in my template:
#####
${XML(tg.splitLines(blogEntry.entryText))}
#####

This is more clear and I am rid of the <br/> at the end.
