Does anyone know of an xPath to JSoup convertor? I get the following xPath from Chrome:
//*[@id="docs"]/div[1]/h4/a and would like to change it into a Jsoup query. The path contains an href I'm trying to reference.

This is very easy to convert manually.
Something like this (not tested)
document.select("#docs > div:eq(1) > h4 > a").attr("href"); Documentation:

Trying to get the href for the first result here: cbssports.com/info/search#q=fantasy%20tom%20brady
Code
Elements select = Jsoup.connect("http://solr.cbssports.com/solr/select/?q=fantasy%20tom%20brady") .get() .select("response > result > doc > str[name=url]"); for (Element element : select) { System.out.println(element.html()); } Result

I am using Google Chrome Version 47.0.2526.73 m (64-bit) and I can now directly copy the Selector path which is compatible with JSoup
Copied Selector of the element in the screenshot span.com is #question > table > tbody > tr:nth-child(1) > td.postcell > div > div.post-text > pre > code > span.com

I have tested the following XPath and Jsoup, it works.
example 1:
[XPath]
//*[@id="docs"]/div[1]/h4/a [JSoup]
document.select("#docs > div > h4 > a").attr("href"); example 2:
[XPath]
//*[@id="action-bar-container"]/div/div[2]/a[2] [JSoup]
document.select("#action-bar-container > div > div:eq(1) > a:eq(1)").attr("href"); 回答4:
Here is the working standalone snippet using Xsoup with Jsoup:
import java.util.List; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import us.codecraft.xsoup.Xsoup; public class TestXsoup { public static void main(String[] args){ String html = "<html><div><a href='https://github.com'>github.com</a></div>" + "<table><tr><td>a</td><td>b</td></tr></table></html>"; Document document = Jsoup.parse(html); List<String> filasFiltradas = Xsoup.compile("//tr/td/text()").evaluate(document).list(); System.out.println(filasFiltradas); } } Output:
[a, b] Libraries included:
xsoup-0.3.1.jar jsoup-1.103.jar

Depends what you want.
Document doc = JSoup.parse(googleURL); doc.select("cite") //to get all the cite elements in the page doc.select("li > cite") //to get all the <cites>'s that only exist under the <li>'s doc.select("li.g cite") //to only get the <cite> tags under <li class=g> tags public static void main(String[] args) throws IOException { String html = getHTML(); Document doc = Jsoup.parse(html); Elements elems = doc.select("li.g > cite"); for(Element elem: elems){ System.out.println(elem.toString()); } } 回答6:
You don't necessarily need to convert Xpath to JSoup specific selectors.
Instead you can use XSoup which is based on JSoup and supports Xpath.
https://github.com/code4craft/xsoup
Here is an example using XSoup from the docs.
@Test public void testSelect() { String html = "<html><div><a href='https://github.com'>github.com</a></div>" + "<table><tr><td>a</td><td>b</td></tr></table></html>"; Document document = Jsoup.parse(html); String result = Xsoup.compile("//a/@href").evaluate(document).get(); Assert.assertEquals("https://github.com", result); List<String> list = Xsoup.compile("//tr/td/text()").evaluate(document).list(); Assert.assertEquals("a", list.get(0)); Assert.assertEquals("b", list.get(1)); }
