这是超文本结构:
Element link = doc.select("div.subtabs p").first();
这似乎并不可行。 我如何选择<代码>p?

带有“代用品”的四级编码事实上不是<代码>p要素的母体,而是<代码>p的相容性。 为了检索<代码>p,请首先参考“连续”的括号:
Element link = doc.select("div#content > p").first();
此外,你需要<条码>和>;条码>符号,以表明你重新选择了一名成年子女。
父母和子女:直接由父母抚养的儿童,例如: div.content > p. 找到了什么内容;以及 身体和体格; * 发现身体上的直系儿童。
如果你今后与一个共同愿景和安全局的甄选人员坐下来,请查看。 JSOUP Optionalorynex cookbook , 其中有一些 n的实例和解释。
<代码>div#content p。 它不是<代码>的儿童。
<<>p>/strong> ,正试图提取的标签不是div的孩子。 它是个兄弟。 括号为content和p。 你们想要的标签是其父母中的第一个p标签。 因此,使用的是doc.select(“div#content > p”);首先();
。
The # means id and > means RHS is a child to LHS. So the statement means get first paragraph which is child to div with id as content
Element link = doc.select("div.subtabs + p")
It finds element immediately preceded by sibling
尝试:
Element link = doc.select("div.subtabs > p").first();
