java - Jsoup:用新行替换标签=>新行以空格开头

Question

我必须用新行替换几个 HTML 标签，例如p 标签如示例代码中所示:

String html = "<p>Zeile1</p><p>Zeile2</p><p>Zeile3</p><p>Zeile4</p>";
Document doc = Jsoup.parse(html);
doc.select("p").append("\\n");
String sanitized = doc.text().replaceAll("\\\\n", System.getProperty("line.separator");
System.out.println(sanitized);

这是输出:

Zeile1
 Zeile2
 Zeile3
 Zeile4

如您所见，我在第 2-4 行中添加了空格。 它们从哪里来？我怎样才能摆脱它们？

像@bdares建议一样，您可以迭代元素:

String html = "<p>Zeile1</p><p>Zeile2</p><p>Zeile3</p><p>Zeile4</p>";
Document doc = Jsoup.parse(html);
StringBuilder b = new StringBuilder();
for (Element p : doc.select("p")) {
    b.append(p.text());
    b.append(System.getProperty("line.separator"));
}
System.out.println(b.toString());

输出:

Zeile1
Zeile2
Zeile3
Zeile4
