Maybe do a simple regex cleanup before you use the template.
Something like the following, which removes whitespace between
> and <, if the whitespace begins with a newline:
import re
...
RE_removeFreeWhitespace = re.compile( r'>[\n\r]+\s*<' )
def removeFreeWhitespace( S ):
return RE_removeFreeWhitespace.sub( r'><', S )
...
templateString = removeFreeWhitespace( templateString )
