使用Groovy MarkupBuilder的HTML,如何优雅地混合标签和文本？

import groovy.xml.MarkupBuilder

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

xml.html {
    head {
        title("My Groovy Page")
    }
    body {
        h1("Welcome to my Groovy page!")
        p("This is a paragraph of text.")
        p {
            strong("This is a bold statement.")
            br()
            em("This is emphasized text.")
        }
    }
}

println writer.toString()
