标签： xpath mule filenames

我正在尝试将xml标记作为文件名的一部分，但我没有获得任何值。难道我做错了什么？我在更改变压器时收到错误或空值

<?xml version="1.0" encoding="UTF-8"?>

你能用它来复杂的XML结构吗？

1 个答案:

答案 0 :(得分：1)

  1. 添加命名空间管理器
  2. 替换文件：file-to-byte-array-transformer with byte-array-to-string-transformer
  3. 修复xpath用法

    4. 更新代码：

    <mule xmlns:file="http://www.mulesoft.org/schema/mule/file"
    xmlns:mulexml="http://www.mulesoft.org/schema/mule/xml" xmlns:email="http://www.mulesoft.org/schema/mule/email"

    xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"
    xmlns:spring="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd

    http://www.mulesoft.org/schema/mule/file http://www.mulesoft.org/schema/mule/file/current/mule-file.xsd
    http://www.mulesoft.org/schema/mule/xml http://www.mulesoft.org/schema/mule/xml/current/mule-xml.xsd">
    <mulexml:namespace-manager
        includeConfigNamespaces="true">
        <mulexml:namespace prefix="ns0"
            uri="http://www.example.com/something.xsd" />
    </mulexml:namespace-manager>
    <flow name="email_notificationFlow">
        <file:inbound-endpoint path="C:\Users\pd00h\Desktop\Knauf\testxML"
            responseTimeout="10000" doc:name="File" />
        <byte-array-to-string-transformer
            doc:name="Byte Array to String" />
        <set-variable variableName="order"
            value="#[xpath3('//ns0:WhsDockets/ns0:WhsDocket/ns0:Reference')]"
            doc:name="Variable" />
        <logger message="#[flowVars.order]" level="INFO" doc:name="Logger" />
        <file:outbound-endpoint path="C:\Users\pd00h\Desktop\Knauf"
            outputPattern="Knauf-#[message.id].xml" responseTimeout="10000"
            doc:name="File" />
    </flow>
</mule>

    示例xml文件：

    <?xml version='1.0' encoding='UTF-8'?>
<ns0:WhsDockets xmlns:ns0="http://www.example.com/something.xsd">
    <ns0:WhsDocket>
        <ns0:Reference>GotIt!</ns0:Reference>
    </ns0:WhsDocket>
</ns0:WhsDockets>
