[英]XPath - all elements inside body
I've been using this query: 我一直在使用此查询:
//*[self::div or self::p or self::span]/text()[normalize-space()][string-length() > 140]
.. but it also fetches content from the non-required elements ( <head>
etc..) so I want to restrict the search within <body>
, but this doesn't work for some reason: ..但它也从不需要的元素(
<head>
等)中获取内容,因此我想将搜索限制在<body>
,但这由于某些原因而无法使用:
//body/*[self::div or self::p or self::span]/text()[normalize-space()][string-length() > 140]
... for this HTML: http://pastebin.com/F4xVDL8Q ...针对此HTML: http : //pastebin.com/F4xVDL8Q
The following part of your XPath indicate that the search should be done only in direct child elements of body
: XPath的以下部分指示,仅应在
body
直接子元素中进行搜索:
//body/*
Since you mean to search in all elements within body
then //*
should've been used instead : 由于您要搜索
body
中的所有元素,因此应该使用//*
代替:
//body//*[...]/text()[...][string-length() > 140]
