在Groovy中使用XmlSlurper解析xml [英] Parse xml using XmlSlurper in Groovy

问题描述

 <？xml version =1.0encoding =UTF -8\" >？; 
< soapenv：Envelope xmlns：soapenv =http://schemas.xmlsoap.org/soap/envelope/xmlns：xsd =http://www.w3.org/2001/XMLSchemaxmlns：的xsi = http://www.w3.org/2001/XMLSchema-instance >

< vixId xsi：type =xsd：int> 13364719< / vixId> 
< / multiRef> 
< / soapenv：Body> 
< / soapenv：Envelope> 
  

此响应存储在 String 名称中

  def xml = new XmlSlurper（）。parseText（xmlMsg）; 
 def vixId = xml.Body.multiRef.vixId.text（）
  

但是问题在阅读 vixId 之前，我想验证 multiRef 标记中的'type'是否是 IdentityModel

我尝试访问类型，如下所示，但徒劳无功： - p>

  def vixId = xml.Body.multiRef。@ type.text（）
  

请注意，我可以在 multiRef id

$ p $ def vixId = xml.Body.multiRef。@ id.text（）


请帮助我访问 type in multiRef tag

编辑：
请注意我想解析类型 code>> multiRef 标记而不使用名称空间，如 multiRef。'@ xsi：type'因为我的 namespace 可能会改变。我想要的是 multiRef 标签有一个属性类型，它的值为 IdentityModel ..只有这样，那么我想读 vixId 。
还要注意，在groovy 1.8中，我使用 multiRef。@ type 解析了它，但没有使用名称空间，但是自从我更新groovy到2.4.7后， p>

PS： - 我在处理xmls方面很新颖

解决方案

默认的XMLSlurper不支持名称空间。这可以通过使用declareNamespace方法声明名称空间来打开。

  def xml = new XmlSlurper（）。parseText（xmlMsg）
 .declareNamespace（'xsi'：'http://www.w3.org/2001/XMLSchema-instance'）
 def vixId = xml.Body.multiRef.vixId.text（）
 println vixId 
 
 def type = xml.Body.multiRef。@'xsi：type'.text（）
 println type 
   
 
输出结果如下：
 
 pre $ $ $ $ $ $ $ 
 ns9：IdentityModel 
  

返回字符串值 ns9：IdentityModel 这是XML中的确切值。如果想剥离命名空间前缀，可以执行类似于 type = type.replace（'ns9：'，''）的事情，最后以IdentityModel结束。

I have an xml response which looks like :-

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soapenv:Body>
      <multiRef xmlns:ns9="http://hero.ar.vixo.in" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" id="id2" soapenc:root="0" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="ns9:IdentityModel">
         <vixId xsi:type="xsd:int">13364719</vixId>
      </multiRef>
   </soapenv:Body>
</soapenv:Envelope>

This response is stored in a String name xmlMsg I am trying to parse it as follows:-

def xml = new XmlSlurper().parseText(xmlMsg);
def vixId = xml.Body.multiRef.vixId.text()

But the problem here is that before reading vixId i want to verify if 'type' in multiRef tag is IdentityModel

I tried accessing type as follows, but in vain :-

def vixId = [e-mail]()

Please note that i am able to access id in multiRef tag using as follows:-

 def vixId = [e-mail]()

Please help me in accessing type in multiRef tag

EDIT: Please note that i want to parse the type in multiRef tag without using name space like multiRef.'@xsi:type' because my namespace could change. All i want is that multiRef tag has a attribute type and that has a value of IdentityModel.. Only if this is there then I want to read vixId. Also note that with groovy 1.8 i was parsing it without namespace using multiRef.@type but it has stopped working ever since i updated groovy to 2.4.7

PS:- I am fairly new in dealing with xmls

解决方案

By default XMLSlurper is not namespace aware. This can be turned on by declaring namespaces with the declareNamespace Method.

def xml = new XmlSlurper().parseText(xmlMsg)
             .declareNamespace('xsi' : 'http://www.w3.org/2001/XMLSchema-instance')
def vixId = xml.Body.multiRef.vixId.text()
println vixId

def type = xml.Body.multiRef.@'xsi:type'.text()
println type

The output is:

13364719
ns9:IdentityModel

This returns the string value ns9:IdentityModel which is the exact value in the XML. If want to strip the namespace prefix, can do something like type = type.replace('ns9:','') to end up with "IdentityModel".
