Groovy markupbuilder标记

Question

有没有办法根据前面的答案修改代码？

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()

因此，如果您添加了一个标记，而不是发送它-就像这样

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

可以是'ol‘或'ul’，例如

Answer 1

您可以依赖于GStrings以及可以通过函数的字符串值调用函数的事实。

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()

Answer 2

你也可以使用invokeMethod，它比上面的更明确，只是稍微长了一点。

builder.html {
  invokeMethod(tag) {
    awaiting.each { 
      li it
} } }
