如何从WSO2 ESB应用程序生成的标记中删除XML属性? [英] How to remove an XML attribute from a tag generated by an WSO2 ESB application?

问题描述

在 WSO2 ESB 中，我还很陌生，并且在生成XML文档时遇到了以下困难.效果很好，但是在生成此文档之后，我必须删除标签上的XML属性.

I am pretty new in WSO2 ESB and I am finding the following difficulty generating an XML document. It works pretty fine but, after that this document is generated I have to remove an XML attribute on a tag.

我具有生成XML文档的以下顺序代码:

I have this sequence code that generates the XML document:

<?xml version="1.0" encoding="UTF-8"?>
<sequence name="transferSequence" trace="disable" xmlns="http://ws.apache.org/ns/synapse">
    <payloadFactory media-type="xml">
        <format>
            <ds:FindTransfer xmlns:ds="http://ws.wso2.org/dataservice">
                <ds:transferId>$1</ds:transferId>
            </ds:FindTransfer>
        </format>
        <args>
            <arg evaluator="xml" expression="$ctx:transferId" xmlns:ds="http://ws.wso2.org/dataservice" xmlns:ns="http://org.apache.synapse/xsd"/>
        </args>
    </payloadFactory>
    <header name="Action" scope="default" value="urn:FindTransfer"/>
    <callout endpointKey="pgrfasEndpoint">
        <source xmlns:ns="http://org.apache.synapse/xsd" xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/" xmlns:s12="http://www.w3.org/2003/05/soap-envelope" xpath="s11:Body/child::*[fn:position()=1] | s12:Body/child::*[fn:position()=1]"/>
        <target xmlns:ns="http://org.apache.synapse/xsd" xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/" xmlns:s12="http://www.w3.org/2003/05/soap-envelope" xpath="s11:Body/child::*[fn:position()=1] | s12:Body/child::*[fn:position()=1]"/>
    </callout>
    <enrich>
        <source clone="true" xmlns:ds="http://ws.wso2.org/dataservice" xmlns:ns="http://org.apache.synapse/xsd" xpath="//ds:transfer"/>
        <target type="body"/>
    </enrich>
    <property name="messageType" scope="axis2" type="STRING" value="application/xml"/>
    <property name="HTTP_METHOD" scope="axis2" type="STRING" value="post"/>
    <!-- Store message into message store -->
    <store messageStore="transferMessageStore"/>
</sequence>

生成这样的XML文档:

that generates an XML document like this one:

<?xml version="1.0" encoding="UTF-8"?>
<transfer xmlns="http://ws.wso2.org/dataservice" username="my_user" password="my_pswd">
    <providerpid>00AB40</providerpid>
    <recipientpid>00AD12</recipientpid>
    <symbol>SMTA1234</symbol>
    <type>SMTA</type>
    <materials>
        <doi>10.0155/1463</doi>
        <doi>10.0155/1464</doi>
    </materials>
</transfer>

是正确的，唯一的问题是 元素已在其上设置了此属性 xmlns ="http://ws.wso2.org/dataservice"

It is correct, the only problem is that the element have this attribute setted on it xmlns="http://ws.wso2.org/dataservice"

我绝对需要以最简单的方式删除此属性(例如，使用 Script 中介器(使用JavaScript)或其他方法.

I absolutly need to remove this attribute in the simplest way (for example using a Script mediator (using JavaScript) or something else.

我该怎么办?

推荐答案

您可以将有效负载/XML传递到XSLT介体中(并使用样式表转换内容)并删除名称空间.

You can pass the payload / XML into a XSLT mediator (and transform the content using a stylesheet) and remove the namespaces.

以下内容对我来说很好.结帐..

The following block works fine to me. checkout..

<xsl:output method="xml" indent="yes"/>
  <xsl:template match="@*|comment()|processing-instruction()">
     <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
     </xsl:copy>
  </xsl:template>
  <xsl:template match="*">
     <xsl:element name="{name()}">
        <xsl:apply-templates select="@*|node()"/>
     </xsl:element>
  </xsl:template>
