Actually
xmliter
populates aSelector
with everything from the position 0 to the tag start, so if we had 100mb before the tag we want to iter it copy those 100mb across all theSelector
objects. Also it just extract this info for the first tag and embed the rest on that, this can cause info crossing.In this PR I kept the regex stuff even tho I think we should use something like
iterparse
.Currently
xmliter_lxml
tests are failing due to it has a different API.
