xelement contacts = new xelement("contacts",     new xelement("contact",         new xelement("name", "patrick hines"),          new xelement("phone", "206-555-0144"),         new xelement("address",             new xelement("street1", "123 main st"),             new xelement("city", "mercer island"),             new xelement("state", "wa"),             new xelement("postal", "68042")         )     ) ); 

output:

<contacts>   <contact>     <name>patrick hines</name>     <phone>206-555-0144</phone>     <address>       <street1>123 main st</street1>       <city>mercer island</city>       <state>wa</state>       <postal>68042</postal>     </address>   </contact> </contacts>
