Using Python Iterparse For Large XML Files (6 answers)

Parsing large XML using iterparse() consumes too much memory. Any alternative? (2 answers)

using lxml and iterparse() to parse a big (+- 1Gb) XML file (3 answers)

Closed 9 months ago.

I am not able to parse XML file of huge size using lxml tree. What I came to know from my research is that lxml iterparse loads the xml file until it gets tag which it is looking for. This is snippet of my code :-

for event, child in etree.iterparse(xml_file,tag='test'):
        print(sys.getsizeof(child))

It is not even reaching print statement and is getting killed. Any help on this matter?
