使用Groovy將具有名稱空間的XML節點添加到現有文檔中

Question

如何將具有名稱空間前綴的xml節點添加到現有文檔？我想建立過什麼，我有這麼遠，如果可能的話：

def rss = new XmlParser().parse(xmlFile) 

rss.channel + { 
item { 
    title("My super atom feed") 
    link(href:"http://www.thecoderscorner.com") 
    description("content of rss item goes here") 
    guid(isPermaLink: "false", "8452") 
} 
} 

我想下面的添加到項目之上：

<event:startDate>Tue, 8 Apr 2014 15:00:00 PDT</event:startDate> 
<event:endDate>Tue, 8 Apr 2014 18:00:00 PDT</event:endDate> 
<event:location>1234 Mrak Hall</event:location> 
<event:isAllDay>false</event:isAllDay>

你應該能夠做這樣的事：

def rss = new XmlParser().parseText(xml) 
rss.channel.item + { 
    item { 
     title("My super atom feed") 
     link(href:"http://www.thecoderscorner.com") 
     description("content of rss item goes here") 
     guid(isPermaLink: "false", "8452") 
     'event:startDate'("Tue, 8 Apr 2014 15:00:00 PDT") 
     'event:endDate'("Tue, 8 Apr 2014 18:00:00 PDT") 
     'event:location'("1234 Mrak Hall") 
     'event:isAllDay'(false) 
    } 
} 
String output = new StringWriter().with { xmlOutput -> 
    new XmlNodePrinter(new PrintWriter(xmlOutput)).with { printer -> 
     preserveWhitespace = true 
     expandEmptyElements = true 
     printer.print(rss) 
    } 
    xmlOutput.toString() 
} 

println output
