sax-js is a streaming XML parser for Node.js that is built on top of the sax C library. It is designed to be fast, low-memory, and easy to use. It is commonly used for parsing large XML files, as it allows you to process the XML data incrementally, rather than loading the entire file into memory at once.

sax-js is a low-level html tree parser and does not provide html query capabilities (like CSS selectors) though it can be useful in HTML tree parsing and serialization.

untangle is a simple library for parsing XML documents in Python. It allows you to access data in an XML file as if it were a Python object, making it easy to work with the data in your code.

To use untangle, you first need to install it via pip by running pip install untangle``. Once it is installed, you can use theuntangle.parse()`` function to parse an XML file and create a Python object.

For example:

import untangle

obj = untangle.parse("example.xml")
print(obj.root.element.child)

You can also pass a file-like object or a string containing XML data to the untangle.parse() function. Once you have an untangle object, you can access elements in the XML document using dot notation.

You can also access the attributes of an element by using attrib property, eg. `obj.root.element['attrib_name']`` untangle also supports xpath-like syntax to access the elements, obj.root.xpath("path/to/element")

It also supports iteration over the elements using obj.root.element.children

for child in obj.root.element.children:
    print(child)

Example Use


const fs = require("fs");
const sax = require("sax");

const xmlStream = fs.createReadStream("example.xml");
const saxParser = sax.createStream(true, {});

saxParser.on("opentag", function(node) {
    console.log(`<${node.name}>`);
});

saxParser.on("closetag", function(nodeName) {
    console.log(`</${nodeName}>`);
});

saxParser.on("text", function(text) {
    console.log(text);
});

xmlStream.pipe(saxParser);
import untangle

obj = untangle.parse("example.xml")

print(obj.root.element.child)
# access attributes:
print(obj.root.element['attrib_name'])
# use xpath:
element = obj.root.xpath("path/to/element")
