XmlSlicer

Slice XML stream using XPath expression

Supported XPath constructs are:

• '/'-axis (child)
• '//'-axis (self-or-descendant)
• node name tests, including namespaces
• all nodes selector: '*'
• predicate test:
• @attribute_name = "literal"

Usage

Instantiate a new XmlSlicer stream and pipe a XML into it. Then XmlSlicer will emit data events on each XPath match. Prior to pass further down the pipe XML fragment can be somehow parsed using internal _XmlSlicer.parse method.

Example

An example of how to use this library is as follows:

var fs = require('fs');
var XmlSlicer = require('xml-slicer');

var fileStream = fs.createReadStream('bookstore.xml');
var xmlSLicer = XmlSlicer({xpath: '//book'});
fileStream.pipe(xmlSLicer).pipe(process.stdout);
