zstreams-xml-writer

Simple streaming XML writer intended to be paired with zstreams-xml-parser for XML transforms. It inputs event objects from the XML parser and outputs XML data.

This has the following caveats:

• processinginstruction, sgmldeclaration, opennamespace, and closenamespace events are ignored.
• attribute events are not used. Attributes are taken from the opentag event.
• No validation is performed; events are expected to be in a valid order.

Example (uppercases all text in the document):

var zstreams = require('zstreams');
var XMLParser = require('zstreams-xml-parser');
var XMLWriter = require('zstreams-xml-writer');
 
zstreams
    .fromFile('./example.xml')
    .pipe(new XMLParser())
    .through(function(event) {
        if (event.type === 'text') {
            event.args[0] = event.args[0].toUpperCase();
        }
        return event;
    })
    .pipe(new XMLWriter())
    .pipe(process.stdout);
