Get number via XPath?

Question

There's a part of the page:

<p>
  349
  <span>
    $
  </span>
</p>

How to get "349"?

Answer 1

There are many XPaths that will select "349" from that XML. Here are a few:

• Select the space-normalized text node children of p :

   normalize-space(/p/text())

• Select the space-normalized substring before the $ in the string value of p :

   normalize-space(substring-before(/p, '$'))

• Select space-normalized, numeric text nodes anywhere in the document:

   normalize-space(//text()[number(.) = .])

All of these XPaths will select "349" as a string as requested. You could also wrap any of the above expressions with a number() function call if you actually want 349 as a number rather than as a string.

由于您没有显示完整的页面，我们没有完整的路径，但试试这个：

 /p/text()
