String noBlankXpath = "//p[@class='p']";
String blankXpath = "//p[@class=' p']";
List<String> noBlankResult = html.xpath(noBlankXpath).all();
System.out.println(noBlankXpath + " ===> " + noBlankResult);
List<String> blankResult = html.xpath(blankXpath).all();
System.out.println(blankXpath + " ===> " + blankResult);结果
//p[@class='p'] ===> [<p class=" p">class blank</p>, <p class="p">class no blank</p>]
//p[@class=' p'] ===> [<p class="p">class no blank</p>]
