YAX 1.2.0

Dependencies

YAX uses Python 3.x and above. It doesn’t depend on any third party module. However, if you have lxml installed you can use it as back-end. (See the documentation about performance.)

Installation

• Download as a zip archive, uncompress and use it.

• pip3 install yax

• (Soon…) Downolad the deb package and install it.

Usage

A simple example which prints all the elements with tagname “a” and containing “href” attribute:

import yax

yr = yax.YAXReader(open("file.xml"))
yr.find("a", {"href": True}).calls(
    lambda e, i: print(yax.element_to_string(e, with_tail=False))  # with_tail only whith lxml!
)
yr.start()

A bit more complex example which filters a gpx record. It prints the elevation values of the trackpoints in a specified area:

import yax

yr = yax.YAXReader(open("route.gpx"))
yr.find("trkpt", {"lat": lambda v: 47 < float(v) < 48,
                  "lon": lambda v: 16 < float(v) < 17},
        keep_children="ele"
        ).calls(lambda e, i: print(e.find("ele").text))
yr.start()

This example shows that it would be erease all unneccessary children from the subtree to save memory but in this case we need the child called “ele”. For more example or the complete reference see the documentation.
