听起来好像您想从HTML转换为纯文本。 如果是这样的话，请查看www.htmlparser.org。下面是一个示例，它从URL中找到的html文件中剥离所有标记。 它使用org.htmlparser.beans.StringBean。

static public String getUrlContentsAsText(String url) {
    String content = "";
    StringBean stringBean = new StringBean();
    stringBean.setURL(url);
    content = stringBean.getStrings();
    return content;
}

值得注意的是，如果您试图在Service Stack项目中完成此操作，那么它已经是一个内置的字符串扩展

using ServiceStack.Text;
// ...
"The <b>quick</b> brown <p> fox </p> jumps over the lazy dog".StripHtml();

〇应该可以

使用这个

  text.replaceAll('<.*?>' , " ") -> This will replace all the html tags with a space.

这

  text.replaceAll('&.*?;' , "")-> this will replace all the tags which starts with "&" and ends with ";" like  , &, > etc.

在Android上试试这个:

String result = Html.fromHtml(html).toString();

接受的答案并不适用于我所指出的测试用例:“a < b or b > c”的结果是“a b or b > c”。

所以，我用TagSoup代替。下面是一个对我的测试用例(以及其他一些测试用例)有效的示例:

import java.io.IOException;
import java.io.StringReader;
import java.util.logging.Logger;

import org.ccil.cowan.tagsoup.Parser;
import org.xml.sax.Attributes;
import org.xml.sax.ContentHandler;
import org.xml.sax.InputSource;
import org.xml.sax.Locator;
import org.xml.sax.SAXException;
import org.xml.sax.XMLReader;

/**
 * Take HTML and give back the text part while dropping the HTML tags.
 *
 * There is some risk that using TagSoup means we'll permute non-HTML text.
 * However, it seems to work the best so far in test cases.

public class Html2Text2 implements ContentHandler {
private StringBuffer sb;

public Html2Text2() {
}

public void parse(String str) throws IOException, SAXException {
    XMLReader reader = new Parser();
    reader.setContentHandler(this);
    sb = new StringBuffer();
    reader.parse(new InputSource(new StringReader(str)));
}

public String getText() {
    return sb.toString();
}

@Override
public void characters(char[] ch, int start, int length)
    throws SAXException {
    for (int idx = 0; idx < length; idx++) {
    sb.append(ch[idx+start]);
    }
}

@Override
public void ignorableWhitespace(char[] ch, int start, int length)
    throws SAXException {
    sb.append(ch);
}

// The methods below do not contribute to the text
@Override
public void endDocument() throws SAXException {
}

@Override
public void endElement(String uri, String localName, String qName)
    throws SAXException {
}

@Override
public void endPrefixMapping(String prefix) throws SAXException {
}


@Override
public void processingInstruction(String target, String data)
    throws SAXException {
}

@Override
public void setDocumentLocator(Locator locator) {
}

@Override
public void skippedEntity(String name) throws SAXException {
}

@Override
public void startDocument() throws SAXException {
}

@Override
public void startElement(String uri, String localName, String qName,
    Attributes atts) throws SAXException {
}

@Override
public void startPrefixMapping(String prefix, String uri)
    throws SAXException {

}

有时html字符串来自xml，带有这样的&lt。在使用Jsoup时，我们需要解析它，然后清理它。

Document doc = Jsoup.parse(htmlstrl);
Whitelist wl = Whitelist.none();
String plain = Jsoup.clean(doc.text(), wl);

而仅使用Jsoup.parse(htmlstrl).text()不能删除标签。
