sax-jsvshtml5-php
sax-js is a streaming XML parser for Node.js that is built on top of the sax C library. It is designed to be fast, low-memory, and easy to use. It is commonly used for parsing large XML files, as it allows you to process the XML data incrementally, rather than loading the entire file into memory at once.
sax-js is a low-level html tree parser and does not provide html query capabilities (like CSS selectors) though it can be useful in HTML tree parsing and serialization.
HTML5 is a standards-compliant HTML5 parser and writer written entirely in PHP. It is stable and used in many production websites, and has well over five million downloads.
HTML5 provides the following features:
- An HTML5 serializer
- Support for PHP namespaces
- Composer support
- Event-based (SAX-like) parser
- A DOM tree builder
- Interoperability with QueryPath
- Runs on PHP 5.3.0 or newer
Note that html5-php is a low-level HTML parser and does not feature any query features like CSS selectors.
Example Use
const fs = require("fs");
const sax = require("sax");
const xmlStream = fs.createReadStream("example.xml");
const saxParser = sax.createStream(true, {});
saxParser.on("opentag", function(node) {
console.log(`<${node.name}>`);
});
saxParser.on("closetag", function(nodeName) {
console.log(`</${nodeName}>`);
});
saxParser.on("text", function(text) {
console.log(text);
});
xmlStream.pipe(saxParser);
