.在XPath中代表当前上下文节点，用于基于当前位置进行相对路径导航，可明确指向当前元素以实现精准定位，常用于相对路径、谓语条件判断、函数参数中，如./span表示当前节点下的span子元素，//div[./@id=’main’]表示id属性为main的div，string(.)返回当前节点文本，..表示父节点可用于向上导航，.与轴和函数结合可提升表达式可读性与精确度，是XPath中基础且关键的语法符号。
是的，XPath中的
.
语法，简单来说，就是代表当前上下文节点。它就像一个指路牌，永远指向你当前正在处理的那个元素或属性。理解这一点，是掌握XPath灵活定位能力的关键一步，因为它让你可以基于当前位置进行相对路径的导航，而不是每次都从文档的根部开始。
解决方案
在我看来，
.
是XPath里最基础也最容易被忽视，但同时又极度强大的一个符号。它的核心作用就是明确指出“我”当前所处的位置。想象一下，你正在一棵巨大的DOM树里穿梭，
.
就是你脚下站立的那片叶子或者那根树枝。
具体来说，当你在编写XPath表达式时，如果没有明确指定一个起始点，那么默认的上下文就是整个文档的根节点。但很多时候，我们希望在某个特定的元素内部进行查找，或者对某个元素本身进行条件判断。这时候，
.
就派上用场了。
比如，你可能有一个
元素，里面有很多
。如果你想找到这个
下面的所有
，你可以写
div/span。但如果你的上下文已经是一个
元素了，你直接写
./span就能达到同样的效果。这看起来只是少写了
div，但实际上它改变了你的思考方式——从“在整个文档中找div再找span”变成了“在当前div中找span”。
更常见的，
.会出现在谓语（
[]）中。当你在一个谓语里使用
.时，它指的是谓语所作用的那个节点本身。举个例子，
//div[./p]表示查找所有包含
p子元素的
div。这里的
.就代表了正在被检查的那个
div元素。如果没有
.，写成
//div[p]效果是一样的，因为在谓语里，当前节点通常是隐式的。但显式地写上
.有时候能让表达式的意图更清晰，尤其是在复杂的嵌套判断中。
它还能用于获取当前节点的文本内容，比如
string(.)就会返回当前节点的文本值。或者在函数中作为参数，比如
contains(., '关键词')，用来判断当前节点的文本是否包含某个关键词。这都是
.作为“当前节点”的体现。
XPath中“.”与“..”的区别与应用场景
在XPath的导航体系里，
.和
..是两个非常基础且频繁使用的相对路径指示符，它们就像是你在文件系统里用
.表示当前目录，用
..表示父目录一样。
.，如前所述，它就是你当前所在的节点。它的主要用途是在相对路径中明确当前上下文，或者在谓语中引用正在被筛选的节点。比如，当你已经定位到一个
元素时，如果你想获取它的
</pre> <div class="contentsignin"></div> </div> <p> 子元素，你可以写 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">./title</pre> <div class="contentsignin"></div> </div> <p>。这明确表示“在当前这个book节点下寻找title”。在谓语里，</p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">//div[./@id='main']</pre> <div class="contentsignin"></div> </div> <p> 意味着寻找那些自身 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">id</pre> <div class="contentsignin"></div> </div> <p> 属性为 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">main</pre> <div class="contentsignin"></div> </div> <p> 的 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">div</pre> <div class="contentsignin"></div> </div> <p>。虽然 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">//div[@id='main']</pre> <div class="contentsignin"></div> </div> <p> 也能达到同样效果，但 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">.</pre> <div class="contentsignin"></div> </div> <p> 的存在有时能帮助我们更好地理解表达式的意图，尤其是在处理更复杂的条件时。</p> <p>而 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">..</pre> <div class="contentsignin"></div> </div> <p> 则代表当前节点的父节点。它允许你向上导航。这在很多场景下都非常有用。想象一下，你定位到了一个 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;"></pre> <div class="contentsignin"></div> </div> <p> 元素，现在你需要找到包含这个 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;"></pre> <div class="contentsignin"></div> </div> <p> 的那个 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;"></pre> <div class="contentsignin"></div> </div> <p> 元素。你就可以使用 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">../..</pre> <div class="contentsignin"></div> </div> <p> 如果 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">author</pre> <div class="contentsignin"></div> </div> <p> 在 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">book/details/author</pre> <div class="contentsignin"></div> </div> <p> 这样的路径下，或者更直接地 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">ancestor::book</pre> <div class="contentsignin"></div> </div> <p>。但如果只是简单的父节点，</p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">..</pre> <div class="contentsignin"></div> </div> <p> 就足够了。比如，</p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">//span[@class='price']/..</pre> <div class="contentsignin"></div> </div> <p> 就能找到包含这个价格 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">span</pre> <div class="contentsignin"></div> </div> <p> 的父元素，它可能是个 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;"><div></pre> <div class="contentsignin"></div> </div> <p> 或者 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;"><li></pre> <div class="contentsignin"></div> </div> <p>。这种向上导航的能力，在处理层级结构不那么固定，或者你需要从子节点反推父节点信息时，显得尤为重要。</p> <p>在我实际工作中，我发现 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">..</pre> <div class="contentsignin"></div> </div> <p> 经常用于从一个特定子元素出发，去获取其父元素的一些属性或内容。例如，</p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">//button[text()='提交']/../@id</pre> <div class="contentsignin"></div> </div> <p>，这表示找到文本为“提交”的按钮，然后获取其父元素的 </p> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">id</pre> <div class="contentsignin"></div> </div> <p> 属性。这种模式在处理表格数据或者列表项时尤其方便，因为你往往是从一个可识别的子元素（如一个链接、一个按钮）开始定位，然后向上回溯到包含它的行或项。</p> <h3>如何利用“.”在复杂XML/HTML结构中精准定位元素？</h3> <div class="code" style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">.</pre> <div class="contentsignin"></div> </div> <p> 在复杂结构中精准定位元素的能力，主要体现在它与谓语（</p> <div class="code"

style="position:relative;padding:0px;margin:0px"> <pre class="brush:php;toolbar:false;">span</pre> <div class="contentsignin"></div> </div> <p> 是相对于 </p> <div class="code"
