xml-flow NPM package - Unexpected XML Parsing Behaviour

Question

Background

I am using xml-flow npm package to parse XML using streams. Issue is that the xml nodes are getting parsed in an unexpected way.

Answer 1

Well! After going through the implementation of these packages, it seems there is no workaround for this problem (I might have missed something) unless explicit support is provided.

I finally decided to write a new logic & ended up writing a new npm package xtreamer which provides xml nodes instead of converting them into JSON objects.

This package exposes a transform stream that can be piped with any readable stream. It expects xml node name in request and emits a custom event xmldata to output the xml node.

The output can the be plugged in to any xml-json npm package as per the requirement to get the final JSON. Check the npm package for further details.

supporting module

I managed to create one more npm package xtagger which uses sax npm package and provides xml structure in following format -

structure: { [name: string]: { [hierarchy: number]: number } };

This package can be used to find the repeating nodes in xml file by considering their hierarchy.
