AWS Lambda precomiled binaries for lxml built for python 2.7 and python 3.6 runtimes.

libxml2-dev and libxslt-dev are not needed as they are included by default in the machines that run lambdas.

1. Put the lxml directory in the root of your lambda package
2. Import lxml and use as usual

from lxml import etree


def handle(event, context):
    return etree.fromstring(event)

This repo contains a build.sh script that's intended to be run in an Amazon Linux docker container, and build lxml for py27 and py36 for use in AWS Lambda.

To build the latest lxml (or any other platform-specific compiled libraries like numpy), run the following:

$ docker run -v $(pwd):/outputs -it lambci/lambda:build-python{2.7|3.6} \
      pip install lxml -t /outputs/

Once you run this, you'll have a folder called lxml (you can ignore the other one with the dist-info), which is the one you are going to place in the root of the lambda package as specified in the example
