<p class="intro"> 这是一位普通老兵的故事，这位老兵没有走上战场，也没有人歌颂他，但他的工作却是面对生与死，他是一名普通的军转干部，没有得到任何荣誉，却仍旧坚守着信仰，永远忠诚。除了他的家人，他的战友，他的故事不被任何人所知，但他的故事正是一代军人、一代军转干部的写照。所以，我来歌颂他，歌颂那一代人。 </p>

- What did you expect to see（期望看到什么）?
4497 - What did you see instead（JsoupXpath给出的结果）?
W/System.err: org.seimicrawler.xpath.exception.XpathSyntaxErrorException: Please check the syntax of your xpath expr or commit a NullPointerException: Attempt to invoke virtual method 'boolean org.jsoup.nodes.Element.isBlock()' on a null object reference
W/System.err: at org.seimicrawler.xpath.JXDocument.selN(JXDocument.java:128) - What version of JsoupXpath are you using（当前版本）?
2.4.2
text()重构后文本比对逻辑没有同步更新导致的。2.4.3已修复。JsoupXpath表现行为和Xpath1.0标准语法以及Chrome的实现保持一致。Chrome的实现可以通过 $x("//*[text()='总字数']//text()")来验证。JsoupXpath的test如下：
