使用Java编辑HTML文档 [英] Edit HTML Document with Java
问题描述
我的java应用程序中存储了一个存储在内存中的HTML文档(在Flying Saucer XHTMLPanel上设置)。
I have an HTML document stored in memory (set on a Flying Saucer XHTMLPanel) in my java application.
xhtmlPanel.setDocument(Main.class.getResource("/mailtemplate/DefaultMail.html").toString());
下面的html文件;
html file below;
<html>
<head>
</head>
<body>
<p id="first"></p>
<p id="second"></p>
</body>
</html>
我想设置 p
元素。我不想为它设置一个架构来使用getDocumentById(),那么我有什么替代方案?
I want to set the contents of the p
elements. I don't want to set a schema for it to use getDocumentById(), so what alternatives do I have?
推荐答案
XHTML是XML,所以任何XML解析器都是我的推荐。我维护 JDOM库,因此自然会建议使用它,但其他库,包括Java中的嵌入式DOM模型将工作。我会使用类似的东西:
XHTML is XML, so any XML parser would be my recommendataion. I maintain the JDOM library, so would naturally recommend using that, but other libraries, including the embedded DOM model in Java will work. I would use something like:
Document doc = new SAXBuilder().build(Main.class.getResource("/mailtemplate/DefaultMail.html"));
// XPath that finds the `p` element with id="first"
XPathExpression<Element> xpe = XPathFactory.instance().compile(
"//p[@id='first']", Filters.element());
Element p = xpe.evaluateFirst(doc);
p.setText("This is my text");
XMLOutputter xout = new XMLOutputter(Format.getPrettyFormat());
xout.output(doc, System.out);
产生以下内容:
<?xml version="1.0" encoding="UTF-8"?>
<html>
<head />
<body>
<p id="first">This is my text</p>
<p id="second" />
</body>
</html>
