xml-tag-stream v0.0.6

Xml-tag-stream

A simple module for streaming xml content split by a given tag name

Basic usage

const XmlTagStream = require('xml-tag-stream');
const stream = require('stream');
const readable = new stream.Readable;

readable
    .pipe(new XmlTagStream('abc'))
    .on('data', console.log.bind(console, '-'))
    .on('end', console.log.bind(console, '-', 'streaming ended'))

readable.push(`
<root>
    <abc>
        123
    </abc>
    <abc x="123">
        <def y="456">
            ghi
        </def>
    </abc>
</root>
`);
readable.push(null);

The following output will get printed:

- <abc>
        123
    </abc>
- <abc x="123">
        <def y="456">
            ghi
        </def>
    </abc>
- streaming ended

The module can be easily combined with some other modules like for example with xml2js and through2

const fs = require('fs');
const XmlTagStream = require('xml-tag-stream');
const through2 = require('through2');
const xmlParser = require('xml2js').Parser();

fs.createReadStream('./some.xml')
    .pipe(new XmlTagStream('abc'))
    .pipe(through2.obj((tag, enc, cb) => xmlParser.parseString(tag, cb)))
    .on('data', console.log.bind(console, '-\n'))
    .on('end', console.log.bind(console, '-\n', 'streaming ended'))
