Question

$("br",top.document).parent().contents().each(function() {
    textx = this.textContent.replace(/s+/g,   )
    if ( this.nodeType == 3 && textx.length ) {
        $(this).wrap( <div id="uniqja__  + numero  +  "></div> )
    }
})

Answer 1

也许有这样的东西?

require  rubygems 
require  nokogiri 

doc = Nokogiri::HTML(your_html)
top_document = doc.xpath("//path_to_an_element")

top_document.
    xpath("//*[br]/text()[string-length(normalize-space()) != 0]").
    wrap("<div id="uniqja__#{numero}"></div>")
