Selax

NPM

A module for streaming XML nodes matched with CSS3 selectors using a through stream. Pipe XML data directly out of a file or network connection into Selax and capture the nodes you want with a CSS3 selector pattern.

Example

 
// Stream temperature nodes from a met.no RSS weather data document (see: http://api.met.no/weatherapi/documentation )
 
var source = fs.createReadStream('weatherdata.rss');
var selax = require('selax');
 
var ax = selax('weatherdata time:first-child temperature');
 
source.pipe(ax);
 
ax.on('readable', function(){
  var node;
 
  while(node = ax.read()){
    console.log('Found matching temperature node: ', node);
  }
});
 
ax.on('end', function(){
  console.log('Finished selecting temperature nodes');
});
 

Notes

Selax is based on libxml2js and emits node objects as plain Javascript objects. Nodes have a type, name, a children array and an attr(name) function for reading attributes.
