Is it possible to do the following in one line list-comprehension?

from lxml import etree
valid_xml_strings = []
for xml_string in xml_strings:
    try:
        etree.fromstring(xml_string)
    except etree.XMLSyntaxError:
        continue
    valid_xml_strings.add(xml_string)

No, list comprehension syntax does not allow `try-except`, and it's for the better – DeepSpace Jun 27 '19 at 22:44
@DeepSpace is it possible to see if something is valid xml without doing a try/except? Or is that the only way. – David542 Jun 27 '19 at 22:44
