    1.xml数据库使用（参考：eXistQuick Start）
    2.xQuery XQuery 首页
   
1.测试开始：
    进入：eXist-> http://demo.exist-db.org/xmldb/db/ 
for $x in doc("/examples2.xml")/exist:result/country return if ($x/population_growth<-1) then <child>{data($x/name)}</child> else <adult>{data($x/name)}</adult>
parent collection: /db
<child > Bosnia and Herzegovina </ child >
<adult > Czech Republic </ adult >
<child > Estonia </ child >
<child > Faroe Islands </ child >
<adult > Hungary </ adult >
<adult > Ireland </ adult >
<child > Latvia </ child >
<adult > Lithuania </ adult >
<child > Romania </ child >
<adult > Russia </ adult >

使用数据：
    http://demo.exist-db.org/xmldb/db/examples2.xml


2：自定义方法：
    使用：http://demo.exist-db.org/sandbox/sandbox.xql
   
declare function local:minPrice(){
  for $x in (1 to 5)
  return <test>{$x}</test>
};

<minPrice>{local:minPrice()}</minPrice>
结果：
<minPrice>
<test>1</test>
<test>2</test>
<test>3</test>
<test>4</test>
<test>5</test>
</minPrice>

解决: 自定义jsXpath 类

js.js
//关键是 jsXpath 类
//使用是 new 并 给属性 domx 值 DOMXml
//var nodes = obj.getPathNodes( xpath ); 就是 xpath语句如://beans/bean
//再 var node = obj.next( nodes )
