如何将dtd验证添加到`xml.etree.cElementTree.iterparse`

Question

I know, that this way of dtd validation before parsing a xml file works:

    from lxml import etree
    context = etree.iterparse(PATH_TO_XML, dtd_validation=True, events=("start", "end"))

But how do I get this to work for the xml.etree.cElementTree.iterparse ?

    from xml.etree.cElementTree import iterparse
    context = iterparse(PATH_TO_XML, ???, events=("start", "end"))

Answer 1

cElementTree is not part of lxml. According to the cElementTree website, DTD Validation is not available to cElementTree.
