Groovy：将XML节点附加到现有的XML文档 [英] Groovy: append an XML Node to an existing XML document

问题描述

我正在使用Groovy，我试图将xml节点插入到用XmlSlurper解析的xml文档中。
我设法在文档的末尾添加节点，但不是我真正需要的地方。

原始文档：

 < xml-fragment xmlns：ser =http://www.bea.com/wli/sb/servicesxmlns：xsi =http：/ /www.w3.org/2001/XMLSchema-instancexmlns：con =http://www.bea.com/wli/sb/pipeline/config> 
< ser：coreEntry isProxy =trueisEnabled =trueisTracingEnabled =false> 
< ser：binding type =SOAPisSoap12 =falsexsi：type =con：SoapBindingTypexmlns：con =http://www.bea.com/wli/sb/services/bindings /配置> 
< con：wsdl ref =bus / src / main / osb / interfaces / apilink / ChargeServices/> 
< con：port> 
< con：name> ChargeServicesPort< / con：name> 
< con：namespace> java：d​​k.tdc.apilink.logic.sessions.interfaces< / con：namespace> 
< / con：port> 
< con：selector type =SOAP body/> 
< / ser：binding> 
< / ser：coreEntry> 
< / xml-fragment> 
  

要添加的片段

  def fragmentToAddXml ='''
< ser：security xmlns：ser =http://www.bea.com/wli/sb/servicesxmlns：xsi =http：/ /www.w3.org/2001/XMLSchema-instancexmlns：con =http://www.bea.com/wli/sb/pipeline/config> hello< / ser：security> 
'''
  

这是我使用的代码。

  def root = new XmlSlurper（）。parseText（file.getText（））
 
 root.'core-entry' .appendNode（fragmentToAddXml）
 def xmlBuilder = new groovy.xml.StreamingMarkupBuilder（）。bind {mkp.yield root} 
  

请注意，新节点应放置在之前节点。

结果应该be：

 < xml-fragment xmlns：ser =http://www.bea.com/wli/sb/服务xmlns：xsi =http://www.w3.org/2001/XMLSchema-instancexmlns：con =http://www.bea.com/wli/sb/pipeline/config> 
< ser：coreEntry isProxy =trueisEnabled =trueisTracingEnabled =false> 
< ser：security xmlns：ser =http://www.bea.com/wli/sb/servicesxmlns：xsi =http://www.w3.org/2001/XMLSchema-instance xmlns：con =http://www.bea.com/wli/sb/pipeline/config> hello< / ser：security> 
 
< ser：binding type =SOAPisSoap12 =falsexsi：type =con：SoapBindingTypexmlns：con =http://www.bea.com/wli/sb /服务/绑定/配置> 
< con：wsdl ref =bus / src / main / osb / interfaces / apilink / ChargeServices/> 
< con：port> 
< con：name> ChargeServicesPort< / con：name> 
< con：namespace> java：d​​k.tdc.apilink.logic.sessions.interfaces< / con：namespace> 
< / con：port> 
< con：selector type =SOAP body/> 
< / ser：binding> 
< / ser：coreEntry> 
< / xml-fragment> 
  

谢谢

解决方案

给定xml（用于测试的字符串）

  def xml ='''< xml-fragment xmlns：ser =http://www.bea.com/wli/sb/servicesxmlns：xsi =http：//www.w3。 org / 2001 / XMLSchema-instancexmlns：con =http://www.bea.com/wli/sb/pipeline/config> 
< ser：coreEntry isProxy =trueisEnabled =trueisTracingEnabled =false> 
< ser：binding type =SOAPisSoap12 =falsexsi：type =con：SoapBindingTypexmlns：con =http://www.bea.com/wli/sb/services/bindings /配置> 
< con：wsdl ref =bus / src / main / osb / interfaces / apilink / ChargeServices/> 
< con：port> 
< con：name> ChargeServicesPort< / con：name> 
< con：namespace> java：d​​k.tdc.apilink.logic.sessions.interfaces< / con：namespace> 
< / con：port> 
< con：selector type =SOAP body/> 
< / ser：binding> 
< / ser：coreEntry> 
< / xml-fragment>'''
  

您要添加的xml as：

  def toadd ='''< ser：security xmlns：ser =http：//www.bea。 com / wli / sb / servicesxmlns：xsi =http://www.w3.org/2001/XMLSchema-instancexmlns：con =http://www.bea.com/wli/sb/pipeline/配置> 
 hello 
< / ser：security>'''
  

然后你可以解析它们（使用 XmlSlurper 设置为通过第二个 true 参数使用名称空间）

  def root = new XmlSlurper（false，true）.parseText（xml）
 fragmentToAdd = new XmlSlurper（false，true）.parseText（toadd） 
  

添加xml以添加到 data 节点（因为您希望它在 data 中，而不是 lastname ）

  root.coreEntry.appendNode（fragmentToAdd）
  

然后打印出来：

  String outxml = groovy.xml.XmlUtil.serialize（root）
 println outxml 
  

其中包含：

 <？xml version =1.0encoding =UTF-8？> 
< xml-fragment> 
< ser：coreEntry xmlns：ser =http://www.bea.com/wli/sb/servicesisTracingEnabled =falseisProxy =trueisEnabled =true> 
< ser：binding xmlns：xsi =http://www.w3.org/2001/XMLSchema-instanceisSoap12 =falsexsi：type =SOAP> 
  < con：name> ChargeServicesPort< / con：name> 
< con：namespace> java：d​​k.tdc.apilink.logic.sessions.interfaces< / con：namespace> 
< / con：port> 
 < / ser：binding> 
< ser：security> 
 hello 
< / ser：security> 
< / ser：coreEntry> 
< / xml-fragment> 
  

我相信这是正确的（未按照我的意愿格式化为100％，但是正确）; - ）

编辑

如果订单很重要，您可以使用 XmlParser >像这样：

  def root = new XmlParser（false，true）.parseText（xml）
 fragmentToAdd = new XmlParser（false，true）.parseText（toadd）
 
 //在第一个coreEntry节点的子节点位置0处插入这个新节点
 root.find {it.name （）=='ser：coreEntry'} .children（）。add（0，fragmentToAdd）
 
 String outxml = groovy.xml.XmlUtil.serialize（root）
 println outxml 
  

I'm using Groovy and I'm trying to insert an xml node into a xml document parsed with XmlSlurper. I manage to add the node at the end of the document but not where I really need to.

Original doc:

<xml-fragment xmlns:ser="http://www.bea.com/wli/sb/services" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:con="http://www.bea.com/wli/sb/pipeline/config"> 
    <ser:coreEntry isProxy="true" isEnabled="true" isTracingEnabled="false">
        <ser:binding type="SOAP" isSoap12="false" xsi:type="con:SoapBindingType" xmlns:con="http://www.bea.com/wli/sb/services/bindings/config">
          <con:wsdl ref="bus/src/main/osb/interfaces/apilink/ChargeServices"/>
          <con:port>
            <con:name>ChargeServicesPort</con:name>
            <con:namespace>java:dk.tdc.apilink.logic.sessions.interfaces</con:namespace>
          </con:port>
          <con:selector type="SOAP body"/>
        </ser:binding>
    </ser:coreEntry>
</xml-fragment>

Fragment to add

def fragmentToAddXml = '''
<ser:security xmlns:ser="http://www.bea.com/wli/sb/services" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:con="http://www.bea.com/wli/sb/pipeline/config">hello</ser:security>
'''

This is the code I'm using.

def root = new XmlSlurper().parseText(file.getText())

root.'core-entry'.appendNode( fragmentToAddXml )
def xmlBuilder = new groovy.xml.StreamingMarkupBuilder().bind{ mkp.yield root }

Please note that the new node should be placed before the "ser:binding" node.

The result should be:

<xml-fragment xmlns:ser="http://www.bea.com/wli/sb/services" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:con="http://www.bea.com/wli/sb/pipeline/config"> 
        <ser:coreEntry isProxy="true" isEnabled="true" isTracingEnabled="false">
            <ser:security xmlns:ser="http://www.bea.com/wli/sb/services" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:con="http://www.bea.com/wli/sb/pipeline/config">hello</ser:security>

            <ser:binding type="SOAP" isSoap12="false" xsi:type="con:SoapBindingType" xmlns:con="http://www.bea.com/wli/sb/services/bindings/config">
              <con:wsdl ref="bus/src/main/osb/interfaces/apilink/ChargeServices"/>
              <con:port>
                <con:name>ChargeServicesPort</con:name>
                <con:namespace>java:dk.tdc.apilink.logic.sessions.interfaces</con:namespace>
              </con:port>
              <con:selector type="SOAP body"/>
            </ser:binding>
        </ser:coreEntry>
    </xml-fragment>

Thanks

解决方案

Given the xml (in a string for testing)

def xml = '''<xml-fragment xmlns:ser="http://www.bea.com/wli/sb/services" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:con="http://www.bea.com/wli/sb/pipeline/config"> 
    <ser:coreEntry isProxy="true" isEnabled="true" isTracingEnabled="false">
        <ser:binding type="SOAP" isSoap12="false" xsi:type="con:SoapBindingType" xmlns:con="http://www.bea.com/wli/sb/services/bindings/config">
          <con:wsdl ref="bus/src/main/osb/interfaces/apilink/ChargeServices"/>
          <con:port>
            <con:name>ChargeServicesPort</con:name>
            <con:namespace>java:dk.tdc.apilink.logic.sessions.interfaces</con:namespace>
          </con:port>
          <con:selector type="SOAP body"/>
        </ser:binding>
    </ser:coreEntry>
</xml-fragment>'''

And the xml you want to add as:

def toadd = '''<ser:security xmlns:ser="http://www.bea.com/wli/sb/services" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:con="http://www.bea.com/wli/sb/pipeline/config">
  hello
</ser:security>'''

Then you can parse them both (with XmlSlurper set to use namespaces via the 2nd true parameter)

def root = new XmlSlurper( false, true ).parseText( xml )
fragmentToAdd = new XmlSlurper( false, true ).parseText( toadd )

Append the xml to add to the data node (as you want it inside data, not lastname)

root.coreEntry.appendNode( fragmentToAdd )

Then print it out:

String outxml = groovy.xml.XmlUtil.serialize( root )
println outxml

Which prints:

<?xml version="1.0" encoding="UTF-8"?>
<xml-fragment>
  <ser:coreEntry xmlns:ser="http://www.bea.com/wli/sb/services" isTracingEnabled="false" isProxy="true" isEnabled="true">
    <ser:binding xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" isSoap12="false" xsi:type="SOAP">
      <con:wsdl xmlns:con="http://www.bea.com/wli/sb/services/bindings/config" ref="bus/src/main/osb/interfaces/apilink/ChargeServices"/>
      <con:port xmlns:con="http://www.bea.com/wli/sb/services/bindings/config">
        <con:name>ChargeServicesPort</con:name>
        <con:namespace>java:dk.tdc.apilink.logic.sessions.interfaces</con:namespace>
      </con:port>
      <con:selector xmlns:con="http://www.bea.com/wli/sb/services/bindings/config" type="SOAP body"/>
    </ser:binding>
    <ser:security>
    hello
  </ser:security>
  </ser:coreEntry>
</xml-fragment>

Which I believe is correct (not formatted 100% as I'd like, but correct) ;-)

Edit

If order is important, you can use XmlParser like so:

def root = new XmlParser( false, true ).parseText( xml )
fragmentToAdd = new XmlParser( false, true ).parseText( toadd )

// Insert this new node at position 0 in the children of the first coreEntry node
root.find { it.name() == 'ser:coreEntry' }.children().add( 0, fragmentToAdd )

String outxml = groovy.xml.XmlUtil.serialize( root )
println outxml
