jsoup在链接href中转义与号 [英] jsoup escaping ampersand in link href
问题描述
JSoup在链接href的URL的查询部分中将&"号转义.鉴于以下示例
JSoup is escaping the ampersand in the query portion of a URL in a link href. Given the sample below
String l_input = "<html><body>before <a href=\"http://a.b.com/ct.html\">link text</a> after</body></html>";
org.jsoup.nodes.Document l_doc = org.jsoup.Jsoup.parse(l_input);
org.jsoup.select.Elements l_html_links = l_doc.getElementsByTag("a");
for (org.jsoup.nodes.Element l : l_html_links) {
l.attr("href", "http://a.b.com/ct.html?a=111&b=222");
}
String l_output = l_doc.outerHtml();
输出为
<html>
<head></head>
<body>
before
<a href="http://a.b.com/ct.html?a=111&b=222">link text</a> after
</body>
</html>
单曲&正在逃逸到& amp; .它不应该保留为&吗? ?
The single & is being escaped to & . Shouldn't it stay as & ?
推荐答案
看来您做不到.我浏览了消息来源，找到了逃生发生的地方.
It seems you can't do it. I went through the source and found the place where the escape happens.
/**
Get the HTML representation of this attribute; e.g. {@code href="index.html"}.
@return HTML
*/
public String html() {
return key + "=\"" + Entities.escape(value, (new Document("")).outputSettings()) + "\"";
}
您会看到它正在使用 Entities.java jsoup采用默认的outputSettings new document("");，这样您就无法覆盖此设置.
There you see it is using the Entities.java jsoup takes the default outputSettings of new document(""); That's way you can't override this settings.
也许您应该为此发布功能请求.
Maybe you should post a feature request for that.
顺便说一句:默认的转义模式设置为base.
Btw: The default Escape mode is set to base.
Documet .java 创建默认的OutputSettings对象，并创建
The Documet.java creates a default OutputSettings Objects, and there it is defined. See:
/**
* A HTML Document.
*
* @author Jonathan Hedley, jonathan@hedley.net
*/
public class Document extends Element {
private OutputSettings outputSettings = new OutputSettings();
// ...
}
/**
* A Document's output settings control the form of the text() and html() methods.
*/
public static class OutputSettings implements Cloneable {
private Entities.EscapeMode escapeMode = Entities.EscapeMode.base;
// ...
}
解决方法(以XML转义):
使用 apache commons lang 项目中的StringEscapeUtils，您可以逃避那些轻松思考.参见:
With the StringEscapeUtils from the apache commons lang project you can escape those thinks easly. See:
String unescapedXml = StringEscapeUtils.unescapeXml(l_output);
System.out.println(unescapedXml);
这将打印:
<html>
<head></head>
<body>
before
<a href="http://a.b.com/ct.html?a=111&b=222">link text</a> after
</body>
</html>
但是，当然，它将取代所有& ...
But of course, it will replace all &...
