我有这样的元素：

<span class="narrowValue">&nbsp;(15,728)</span>

我是这样刮的：

  @department_hash = Hash.new {|h,k| h[k]=[]}
  department.css('.narrowValue').each do | department |
    @department_hash["department"] << department.text
  end

并得到这样的结果：

{"department"=>[" (15,725)", " (243,256)", " (510,337)", " (46,002)", " (14,109)", " (358)", " (5,787)", " (19,818)"]}

但我不需要括号。

我怎样才能只得到数字？

在将文本推送到数组之前，去掉括号。

@department_hash = Hash.new {|h,k| h[k]=[]}
department.css('.narrowValue').each do | department |
  @department_hash["department"] << department.text.gsub(/^[() \u00a0]+|[() \u00a0]+$/, '')
end

或者，您可以使用以下正则表达式：

/^[()[:space:]]+|[()[:space:]]+$/

[[:space:]]匹配 nbsp，但\s不匹配 nbsp。

使用以下修改：

@department_hash["department"] << department.text.gsub(/[^\d,]/,"")
