在XQuery中：
declare namespace output = "http://www.w3.org/2010/xslt-xquery-serialization";
宣告選項output:method 'text';
宣告選項output:item-separator ' ' 。
/Resources/Resource/string-join((UID, Name), ', ')
uj5u.com熱心網友回復：
可以在一個單一的Xpath 1.0運算式上完成
concat(concat(/Resource[1]/UID/text(), ",", /Resource[1]/Name/text()), " ", concat(/Resource[2]/UID/text(), ", ", /Resource[2]/Name/text() )
其形式是
concat(concat(elem1," ," elem2), " ",concat(elem3," ," elem4)
在命令列上進行測驗
xmllint --xpath 'concat(concat(/Resource[1]/UID/text(), ",", /Resource[1]/Name/text()), " ", concat(/Resource[2]/UID/text(), ", ", /Resource[2]/Name/text()) ' tmp.xml ; echo
結果：
14,娛樂 12,電影
