尝试使用Apache Tika和XPath获取属性值

Question

XPathParser  xhtmlParser = new XPathParser ("xhtml", XHTMLContentHandler.XHTML);
Matcher anchorLinkContentMatcher = xhtmlParser.parse("//xhtml:a/@xhtml:href/text()");
ContentHandler handler = new MatchingContentHandler(
    new ToHTMLContentHandler(), anchorLinkContentMatcher);
HtmlParser parser = new HtmlParser();
ParseContext pcontext = new ParseContext();
    
try {
    parser.parse(urlContentStream, handler, new Metadata(),pcontext);
    System.out.println(handler);
}
catch (Exception e)
{....}

我尝试了以下不同的XPath：

//xhtml:a/@xhtml:href
//xhtml:a/href/text()
//xhtml:a/href
//@xhtml:href/text()

Answer 1

//xhtml:a/@href
