我正在尝试解析从磁盘读取的Simple XMl文件并将其转换为JSON并使用Mulesoft将其存储回文件。
这就是mule flow.xml的样子
<file:connector name="File" autoDelete="false" streaming="true" validateConnections="true" doc:name="File"/>
<file:connector name="File1" outputPattern="sample1.txt" autoDelete="false" streaming="true" validateConnections="true" doc:name="File"/>
<flow name="datatranformerFlow">
<file:inbound-endpoint path="C:\Madhu" name="sample.xml" responseTimeout="10000" doc:name="File" connector-ref="File"/>
<file:file-to-string-transformer mimeType="application/xml" doc:name="File to String"/>
<splitter expression="#[xpath3('/Names/Name')]" doc:name="Splitter"/>
<json:xml-to-json-transformer doc:name="XML to JSON"/>
<file:outbound-endpoint path="C:\Madhu\GV dev documents\WD files" connector-ref="File1" responseTimeout="10000" doc:name="File"/>
</flow>
我尝试解析的示例xml文件看起来像
<Names>
<Name>
<title>bnbnbha</title>
<firstname>aa</firstname>
<lastname>aaa</lastname>
</Name>
<Name>
<title>bjkjkjk</title>
<firstname>bb</firstname>
<lastname>bbb</lastname>
</Name>
<Name>
<title>hjhjhc</title>
<firstname>cc</firstname>
<lastname>ccc</lastname>
</Name>
<Name>
<title>djkjkj</title>
<firstname>dd</firstname>
<lastname>ddd</lastname>
</Name>
</Names>
当我运行mule项目时,我得到一个异常
INFO 2016-07-29 11:56:25,287 [[datatranformer] .File.receiver.01] org.mule.transport.file.FileMessageReceiver:在文件中获取的锁:C:\ Madhu \ sample.xml INFO 2016-07-29 11:56:26,193 [[datatranformer] .datatranformerFlow.stage1.02] org.mule.routing.ExpressionSplitter:表达式不计算为可拆分的类型:java.lang.String 错误:&#39;意外的角色&#39; b&#39; (代码98)在prolog;预期&#39;&lt;&#39; 在[row,col {unknown-source}]:[2,3]&#39; ERROR 2016-07-29 11:56:26,272 [[datatranformer] .datatranformerFlow.stage1.02] org.mule.exception.DefaultMessagingExceptionStrategy:

我有什么问题吗?

如果您的目的只是读取XML文件,将其转换为JSON,并将其存储到文件(无需进一步处理),然后删除文件到字符串转换器和 Splitter 流量控制。
所以你的配置变成这样:
<flow name="datatranformerFlow">
<file:inbound-endpoint path="C:\Madhu" name="sample.xml" responseTimeout="10000" doc:name="File" connector-ref="File"/>
<json:xml-to-json-transformer doc:name="XML to JSON"/>
<file:outbound-endpoint path="C:\Madhu\GV dev documents\WD files" connector-ref="File1" responseTimeout="10000" doc:name="File"/>
</flow>

你能使用#[xpath3(&#39; / Names&#39;)]

只需删除拆分器表达式,如前所述,您只想将此文件转换为csv,请检查以下流程:
<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns:json="http://www.mulesoft.org/schema/mule/json"
xmlns:file="http://www.mulesoft.org/schema/mule/file" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

<file:connector name="File1" outputPattern="sample1.txt" autoDelete="false" streaming="true" validateConnections="true" doc:name="File"/>
<flow name="datatranformerFlow">
<file:inbound-endpoint path="C:\madhu" connector-ref="File" responseTimeout="10000" doc:name="File"/>
<file:file-to-string-transformer doc:name="File to String"/>
<json:xml-to-json-transformer mimeType="application/json" doc:name="XML to JSON"/>
<logger message="payload--> #[message.payloadAs(java.lang.String)]" level="INFO" doc:name="Logger"/>
<file:outbound-endpoint path="C:\Madhu\GV dev documents\WD files" connector-ref="File1" responseTimeout="10000" doc:name="File"/>
</flow>
</mule>
希望这有帮助!
