javascript的XML解析

来源：互联网发布：linux配置网关编辑：程序博客网时间：2024/05/17 06:28

由于需要熟悉mirth,其中JavaScript部分是非常重要的,特别是其XML解析部分,不知道

var getPatientByMayIDResponseXML = new XML(getPatientByMayIDResponse);

实例HL7中的XML类

var temp1 = getPatientByMayIDResponseXML.*.toString();

<soap:Header xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"/><soap:Body xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><ns2:getPatientByMapIDResponse xmlns:ns2="http://services.cxf.shengjy.vico.com/"><return><objectList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:patient"><id>321</id><name>bbb</name><sex>f</sex><mapToID>11</mapToID></objectList></return></ns2:getPatientByMapIDResponse></soap:Body><span style="font-family:Arial;BACKGROUND-COLOR: #ffffff"></span>

.*表示该XML文本本身,返回的temp1会显示该节点下的XML文本,如果是最初的XML文本则会去掉申明

var temp2 = getPatientByMayIDResponseXML..*toString();

<soap:Header xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"/><soap:Body xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><ns2:getPatientByMapIDResponse xmlns:ns2="http://services.cxf.shengjy.vico.com/"><return><objectList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:patient"><id>321</id><name>bbb</name><sex>f</sex><mapToID>11</mapToID></objectList></return></ns2:getPatientByMapIDResponse></soap:Body><ns2:getPatientByMapIDResponse xmlns:ns2="http://services.cxf.shengjy.vico.com/"><return><objectList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:patient"><id>321</id><name>bbb</name><sex>f</sex><mapToID>11</mapToID></objectList></return></ns2:getPatientByMapIDResponse><return><objectList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:patient"><id>321</id><name>bbb</name><sex>f</sex><mapToID>11</mapToID></objectList></return><objectList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:patient"><id>321</id><name>bbb</name><sex>f</sex><mapToID>11</mapToID></objectList><id>321</id>321<name>bbb</name>bbb<sex>f</sex>f<mapToID>11</mapToID>11

..*将会一级一级的解析其所有的子节点并返回

var aa = getPatientByMayIDResponseXML..*::['name'].toString();

::['']的写法与..*连用

bbb

var aa = getPatientByMayIDResponseXML..*['name'].toString();

bbb

返回值相同,都正确解析了最底层的节点
那么两者有什么不同之处呢?

var aa = getPatientByMayIDResponseXML.*['name'].toString();

var aa = getPatientByMayIDResponseXML.*::['name'].toString();

两个都返回空值,所以没搞清楚.*有什么用处,写和没写效果没什么区别的样子
