The installed module exposes the Parser object, which is then used to read XML.

Here at the time of creating the object, an option is provided to override this default setting. In this example attributes will be stored under ATTR key. This is simply done to improve readability. The approach is similar to parsing XML from a file.

The XML response is then read by xml2js. Reading such large files by loading the contents in the memory at one go can have detrimental effects on the system. The solution to this problem is to read the large files as streams. The node-xml-stream parser object has the following events associated with it :. The same XML file from before is being used here except this time the data is being read in streams. The events that are being used to parse this XML are opentagclosetagtext and finish.

You understand it. If the library doesn't know the schema, it must either "use and abuse" arrays, extra layers of objects, special attribute names, or all three. The only alternative is to employ a variable output schema. That keeps it simple at first, as we saw above, but you'll quickly find yourself writing a great deal of conditional code.

Reading XML in Node.js

Consider what happens if children with the same tag name are collapsed into a list, but only if there are more than one:. TL;DR: it's harder than it looks. All "use and abuse" arrays, extra layers of objects, members with names that didn't appear in the original XML, or all three. As xml2js' documentation statesyou can configure the parser to not abuse of arrays, by setting the property explicitArray to false important: it has to be a boolean value as the string "false" will just not work!

This way, you should be able to access your JSON properties in a much easier way. I hope this helps anyone.
