使用Java编程生成HTMLDocument [英] Programmatic HTMLDocument generation using Java

问题描述

有谁知道如何在Java中以编程方式生成HTMLDocument对象，而无需通过外部生成String，然后使用HTMLEditorKit＃read来解析它？我要问的两个原因是：首先，我的HTML生成例程需要非常快，我假设将字符串解析为内部模型比直接构建此模型成本更高。第二，面向对象的方法可能会导致更简洁的代码。

我还应该提到，出于授权的原因，我不能诉诸使用任何与JVM一起提供的库。

谢谢，
Tom

$ b $一个面向对象的方法是使用一个叫做

的rel = noreferrer> ECS 。

这是相当简单的图书馆，并且没有变化多少年。然后，HTML 4.01规范也没有改变;）我使用了ECS，并认为它比仅使用Strings或StringBuffers / StringBuilders生成大型HTML片段要好得多。

小例子：

  Option optionElement = new Option（）; 
 optionElement.setTagText（bar）; 
 optionElement.setValue（foo）; 
 optionElement.setSelected（false）; 
  

optionElement.toString（） ：

 < option value ='foo'> bar< / option> 
  

该库支持HTML 4.0和XHTML。首先困扰我的唯一的事情是，与XHTML版本相关的类的名称以小写字母开头：选项， input ， a ， tr 等等，这违背了最基本的Java约定。但是如果你想使用XHTML，那么你可以习惯这种方式;至少我做了，令人惊讶的快。

Does anyone know how to generate an HTMLDocument object programmatically in Java without resorting to generating a String externally and then using HTMLEditorKit#read to parse it? Two reasons I ask:

Firstly my HTML generation routine needs to be very fast and I assume that parsing a string into an internal model is more costly than directly constructing this model.

Secondly, an object-oriented approach would likely result in cleaner code.

I should also mention that, for licensing reasons, I can't resort to using any libraries other than those shipped with the JVM.

Thanks, Tom

解决方案

One object-oriented approach is to use a library called ECS.

It is quite simple library, and has not changed for ages. Then again, the HTML 4.01 spec has not changed either ;) I've used ECS and consider it far better than generating large HTML fragments with just Strings or StringBuffers/StringBuilders.

Small example:

Option optionElement = new Option();
optionElement.setTagText("bar");
optionElement.setValue("foo");
optionElement.setSelected(false);   

optionElement.toString() would now yield:

<option value='foo'>bar</option>

The library supports both HTML 4.0 and XHTML. The only thing that initially bothered me a lot was that names of classes related to the XHTML version started with a lowercase letter: option, input, a, tr, and so on, which goes against the most basic Java conventions. But that's something you can get used to if you want to use XHTML; at least I did, surprisingly fast.
