使用Cyber​​neko解析html以查找“ div”标签

[英]Parsing html with cyberneko to find a 'div'-tag

I need one specific 'div'-tag (identified by 'id') from a html site. 我需要一个来自html网站的特定“ div”标签(由“ id”标识)。 To parse the page I'm using cyberneko. 为了解析页面,我正在使用cyberneko。

    def doc = new XmlParser( new org.cyberneko.html.parsers.SAXParser() ).parse(htmlFile)
    divTag = doc.depthFirst().DIV.find{ it['@id'] == tagId  }

So far no problem, but at the end I don't need XML, but the original content of the whole 'div' tag. 到目前为止没有问题,但是最后我不需要XML,而是整个'div'标签的原始内容。 Unfortunatly I can't figure out how to do this... 不幸的是我不知道该怎么做...

EDIT: Responding to first comment. 编辑:回应第一条评论。

This works: 这有效:

def html = """
  <body>
        <div id="breadcrumbs">
            <b>
            crumb1
            </b>
        </div>
</body>
"""

def doc = new XmlSlurper(new org.cyberneko.html.parsers.SAXParser()).parseText(html)
divTag = doc.BODY.DIV.find { it.@id == 'breadcrumbs'  }
println "" << new groovy.xml.StreamingMarkupBuilder().bind {xml -> xml.mkp.yield divTag}

It looks like cyberneko will return a well formed HTML document, regardless of whether the original markup was. 无论原始标记是否存在,cyberneko都将返回格式正确的HTML文档。 ie, doc's root will be a HTML element, and there will also be a HEAD element. 即doc的根将是HTML元素,并且还将有HEAD元素。 Neat. 整齐。

This is a simple test based on noah's answer - unfortunatly it does not (yet) work :( 这是一个基于诺亚回答的简单测试-不幸的是,它还没有运行:(

    def html = """
      <body>
            <div id="breadcrumbs">
                <b>
                crumb1
                </b>
            </div>
    </body>
    """

    def doc = new XmlSlurper( new org.cyberneko.html.parsers.SAXParser() ).parseText(html)
    println "document: $doc"
    def htmlTag = doc.DIV.find {
        println "-> $it"
        it['@id'] == "breadcrumbs"
    }
    println htmlTag
    assert htmlTag
