Question

What is the correct syntax for using HTML builder with mixed content in Groovy 1.7?

Answer 1

+2 A:

I found a lot of the stuff in that example to be out dated. The syntax for mixed hrefs and the [] around the paragraph do not work for me.

For mixed content, you need to use the special keyword 'mkp.yield'. There is also an 'mkp.yieldUnescaped' if you don't want escaping. There are some other functions you can do with mkp as well.

This example does work and shows using mixed content:

def builder = new groovy.xml.MarkupBuilder()
builder.html {     
  head {         
    title"XML encoding with Groovy"     
  }     
  body {
    h1"XML encoding with Groovy"   
    p"this format can be used as an alternative markup to XML"      

    a(href:'http://groovy.codehaus.org', "Groovy")

    p {     
      mkp.yield "This is some"
      b"mixed"   
      mkp.yield " text. For more see the"
      a(href:'http://groovy.codehaus.org', "Groovy")
      mkp.yield "project"    
    }      
    p "some text"    
  } 
}

Output:

<html>
  <head>
    <title>XML encoding with Groovy</title>
  </head>
  <body>
    <h1>XML encoding with Groovy</h1>
    <p>this format can be used as an alternative markup to XML</p>
    <a href='http://groovy.codehaus.org'&gt;Groovy&lt;/a&gt;
    <p>This is some
      <b>mixed</b> text. For more see the
      <a href='http://groovy.codehaus.org'&gt;Groovy&lt;/a&gt;project
    </p>
    <p>some text</p>
  </body>
</html>

Thank you very much for that very thorough answer! I haven't had a chance to try it yet, but I assume that will work. This "yield" syntax seems a bit unelegant and crufty though :(

Answer 2

A:

I think this works better:-

def writer = new StringWriter()  
    def builder = new groovy.xml.MarkupBuilder(writer)
    builder.html {
        head {
            title"Report"
        }
        body {
            h1"XML encoding with Groovy"
            p"this format can be used as an alternative markup to XML"

            // an element with attributes and text content /
            a(href:'http://groovy.codehaus.org', "Groovy")

            // mixed content /
            p() {
                "This is some"
                "mixed"
                "text. For more see the"
                a(href:'http://groovy.codehaus.org', "Groovy")
                "project"
            }
            p "some text"
        }
    }

Result is:-

<html>
  <head>
    <title>Report</title>
  </head>
  <body>
    <h1>XML encoding with Groovy</h1>
    <p>this format can be used as an alternative markup to XML</p>
    <a href='http://groovy.codehaus.org'&gt;Groovy&lt;/a&gt;
    <p>
      <a href='http://groovy.codehaus.org'&gt;Groovy&lt;/a&gt;
    </p>
    <p>some text</p>
  </body>
</html>
