JarCastingMoulder-j
A (relatively) tiny jQuery-like HTML templating library written in Java. In a nutshell, here's how to use moulder:
- parse a document
- select one or more elements (using jQuery's selectors syntax)
- apply one or more modifiers on the previous selection (add/remove/modify attribute, set text, repeat, ...)
- go back to 2 to alter as many other elements as needed
- profit !
Using this library
To use this library in your projects, just add the following to the dependencies section of your pom.xml (moulder is deployed in central):
<dependency>
<groupId>com.plecting</groupId>
<artifactId>moulder</artifactId>
<version>1.0.0</version>
</dependency>
I've compiled some simple and elementary use cases in this gist, and some more complex and advanced use cases in this gist.
Here's a quick sample of how moulder can be used to manipulate html:
Given this markup:
<html>
<body>
<h1>dummy text to be replaced</h1>
</body>
</html>
This moulder based snippet:
Document doc = Jsoup.parse(HTML);
MoulderShop m = new MoulderShop();
List<String> items = Arrays.asList("summer", "autumn", "winter", "spring");
m.register("h1",
repeat(items.size()),
text(seq(items)),
attr("class", seq("even", "odd").cycle()),
append("<p>content</p>")
);
m.process(doc);
Will generate the following:
<html>
<head>
</head>
<body>
<h1 class="even">Spring</h1>
<p>content</p>
<h1 class="odd">Summer</h1>
<p>content</p>
<h1 class="even">Autumn</h1>
<p>content</p>
<h1 class="odd">Winter</h1>
<p>content</p>
</body>
</html>
Or in plain english:
- repeat the h1 element as many times as there are items in the list
- For each generated h1 element, set it's class to even or odd
- Also set it's text content to the corresponding season
- And finally, append a paragraph after it
Building
You need a Java 5 (or newer) environment and Maven 3 installed:
$ mvn --version
Apache Maven 3.0-beta-1 (r935667; 2010-04-19 19:00:39+0200)
