RXML-Parser

Parsing XML gracefully with RxJava!

Overview

We all hate XML parsing (at least I do)

We all love RxJava (at least I do)

RXML-Parser provides an easy way of parsing XML files through an Rx API

---

Features

• Parse of Java built-in Document and Node interface
• Easy API
• No need of instantiating new objects

How to start

You'll need some XML content. You can find a couple of them in the sample project (under src/test/resources/xml)

When you have your file you just have to convert it to a Document. You can use the following snippet for that:

private static Document loadDocument(String path) throws Exception {
    File file = new File(path);
    DocumentBuilderFactory dbFactory
            = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
    return dBuilder.parse(file);
}

Once you have your Document decide which nodes you want to access. For example in the simpleNote test I want to get all nodes (using RXMLParser.WILD_CARD) that are under note node so I will use:

Observable<Node> obsNodes = RXMLParser.getNodes(document, "note", RXMLParser.WILD_CARD)

and that will give me an Observable that emits the requested nodes. At that point you have a regular Observable so you can use all RxJava stuff! For example, if I wanted to get all nodes that fulfills a condition I could use

Observable<Node> euNodes = RXMLParser.getNodes(document, "CATALOG", "CD")
        .filter(cdNode -> RXMLParser.getNodes(cdNode, "COUNTRY")
                .map(Node::getTextContent)
                .map(country -> country.equals("EU"))
                .toBlocking()
                .first())

You can find more examples under sample project
