Groovy 标记生成器标签

Question

有没有办法修改之前答案中的代码

import groovy.xml.MarkupBuilder

def writer = new StringWriter()
def builder = new MarkupBuilder(writer)

def awaiting = ['one', 'two', 'three']

builder.html {
    ul {
        awaiting.each { 
            li(it.toString())
        }
    }
}

println writer.toString()

这样，如果您添加标签而不是发送它 - 就像

    builder.html{
tag{
    awaiting.each{}
    }
} return result

例如可以是“ol”或“ul”

Answer 1

您可以依赖 GString，并且可以通过其字符串值调用函数。

import groovy.xml.MarkupBuilder

def writer = new StringWriter()
def builder = new MarkupBuilder(writer)

def awaiting = ['one', 'two', 'three']
def tag = 'ol'

builder.html {
    "$tag" {
        awaiting.each { 
            li(it.toString())
        }
    }
}

println writer.toString()
