The best node module for XML parsing [closed]

You can try xml2js. It's a simple XML to JavaScript object converter. It gets your XML converted to a JS object so that you can access its content with ease.

Here are some other options:

libxmljs
xml-stream
xmldoc
cheerio – implements a subset of core jQuery for XML (and HTML)

I have used xml2js and it has worked fine for me. The rest you might have to try out for yourself.

This answer concerns developers for Windows. You want to pick an XML parsing module that does NOT depend on node-expat. Node-expat requires node-gyp and node-gyp requires you to install Visual Studio on your machine. If your machine is a Windows Server, you definitely don't want to install Visual Studio on it.

So, which XML parsing module to pick?

Save yourself a lot of trouble and use either xml2js or xmldoc. They depend on sax.js which is a pure Javascript solution that doesn't require node-gyp.

Both libxmljs and xml-stream require node-gyp. Don't pick these unless you already have Visual Studio on your machine installed or you don't mind going down that road.

Update 2015-10-24: it seems somebody found a solution to use node-gyp on Windows without installing VS: https://github.com/nodejs/node-gyp/issues/629#issuecomment-138276692

January 5, 2015 - Not all APIs return JSON so it is the application developers responsibility to handle the XML. Lucky for us there is a convenient package for Node.js called xml2js that will handle all the parsing for us.

r/node on Reddit: How to parse large XML file (2–3GB) in Node.js within a few seconds?

July 25, 2025 -

I have a large XML file (around 2–3 GB) and I want to parse it within a few seconds using Node.js. I tried packages like xml-flow and xml-stream, but they take 20–30 minutes to finish.

Is there any faster way to do this in Node.js or should I use a different language/tool?

context:

I'm building a job distribution system. During client onboarding, we ask clients to provide a feed URL (usually a .xml or .xml.gz file) containing millions of <job> nodes — sometimes the file is 2–3 GB or more.

I don't want to fully process or store the feed at this stage. Instead, we just need to:

Count the number of <job> nodes
Extract all unique field names used inside the <job> nodes
Display this info in real-time to help map client fields to our internal DB structure

This should ideally happen in a few seconds, not minutes. But even with streaming parsers like xml-flow or sax, the analysis is taking 20–30 minutes.

I stream the file using gzip decompression (zlib) and process it as it downloads. so I'm not waiting for the full download. The actual slowdown is from traversing millions of nodes, especially when different job entries have different or optional fields.

I've had to deal with things like this in the past. Some PLC controllers were outputting massive XML objects. My trick, and this might not be your case, was to ignore the XML part of the XML. I loaded the entire file into memory and used a series of regex queries to find the data I needed and just pulled that. Do you actually need to "use" the XML or are you just looking for parts in it?

Even without starting to parse it, you will need to be able to read from disk at more than 1GB /s

All three usable packages convert XML strings into plain JavaScript objects—but they do it differently. Uses a recursive descent parser. By default, it preserves attribute names under a @_ prefix and text content under #text.
