Fruit is a Java library that can be used to convert html to Java Objects and back follow a certain rule.
So, in short, Fruit for Html just like Gson for Json.
Fruit was inspired by Goolge's Gson, and powered by jsoup.
Let me suppose that you have a html file, just like below:
<html>
<head></head>
<body>
<div id='only'>Apple <em>is my favorite fruit.</em></div>
<img src='http://dwz.cn/5USjpv' class="apple"/>
<a href='https://ghui.me' class="author"> ghui</a>
<div id='fruits'>
<div class="fruit" id="1">
<strong class="name">apple</strong>
<strong class="color">red</strong>
</div>
<div class="fruit" id="2">
<strong class="name">orange</strong>
<strong class="color">green</strong>
</div>
<div class="fruit" id="3">
<strong class="name">banana</strong>
<strong class="color">yellow</strong>
</div>
<div class="fruit" id="4">
<strong class="name">pear</strong>
<strong class="color">yellow</strong>
</div>
<div class="fruit" id="5">
<strong class="name">peach</strong>
<strong class="color">pink</strong>
</div>
</div>
</body>
</html>And now you want to parse the document to a Java Object named FruitInfo, like below:
public class FruitInfo {
private String favorite;
private String favoriteOne;
private String favoriteHtml;
private String img;
private String blog;
private List<Item> items;
public static class Item {
private String name;
private String color;
private int id;
}
}What would you do ? No bullshit, with Fruit you can just do like below:
- Add
Pickannotation to FruitInfo.
public class FruitInfo {
@Pick("div#only")
private String favorite;
@Pick(value = "div#only", attr = Attrs.OWN_TEXT)
private String favoriteOne;
@Pick(value = "div#only", attr = Attrs.HTML)
private String favoriteHtml;
@Pick(value = "img.apple", attr = Attrs.SRC)
private String img;
@Pick(value = "a.author", attr = Attrs.HREF)
private String blog;
@Pick("div.fruit")
private List<Item> items;
public static class Item {
@Pick("strong.name")
private String name;
@Pick(".color")
private String color;
@Pick(attr = "id")
private int id;
}
}- Just do pick from the html.
FruitInfo fruitInfo = new Fruit().fromHtml(htmlStr, FruitInfo.class);Note: There are two field of the Pick annotation, the value field is a
css-like element selector, For more details, visit here.
The second field is optional, and it's default value istext. You can assign ownText(direct text), src, href, and any other exist attr-name in your html tree to it. Just run the junit test code for more detail.
