[lxml] a 'tail' problem

Feb. 24, 2015

      I have a "tail" problem with the following XML fragment

<lg>
    <l>WHo doth desire the trump of fame, to sound vnto the Skies,</l>
    <l><pb/>Or els who seekes the holy place, where mighty Ioue he
lies,</l>
    <l>He must not by deceitfull mind, nor yet by puissant strength,</l>

</lg>

I want to turn the <pb> tag from child to previous sibling of <l> and use
this code

for element in tree.iter():
	if element.tag == 'pb':
		parent = element.getparent()
		grandparent = parent.getparent()
		position = grandparent.index(parent)
		parent.text = element.tail
		grandparent.insert(position , (element))

Some of it works but it fails to get rid of the pb tail and produces this
output:

<lg>
    <l>WHo doth desire the trump of same, to sound vnto the skies,</l>
    <pb/>Or els who seekes the holy place, where mighty Ioue he lies,
<l>Or els who seekes the holy place, where mighty Ioue he lies,</l>
    <l>He must not by deceitfull mind, nor yet by puissant strength,</l>

</lg>

If there is a with_tail=False solution, I don't know where to stick the
command.
