[英]Iterate mediator-expression using property
I want to use iterator mediator by passing property as Xpath in expression. 我想通过在表达式中将属性作为Xpath传递来使用迭代器介体。 is that possible in wso2 esb
在wso2 esb中有可能吗
<property name="listXPath" value="//records/record"></property>
<iterate continueParent="true" expression="get-property('listXPath')" id="EventListId" sequential="true">
<target>
<sequence>
<log>
<property name="inside Iterator for Each List" expression="$body"></property>
</log>
</sequence>
</target>
</iterate>
i want the result as iterator should accept property as a expression parameter 我希望结果作为迭代器应接受属性作为表达式参数
Guess this would not work. 猜猜这行不通。 But You can try to use Sequence template and pass your Xpath as a param to a call-template mediator.
但是您可以尝试使用Sequence模板,并将Xpath作为参数传递给调用模板介体。
You can set XPath for expression in iterate mediator. 您可以在迭代介体中设置用于表达的XPath。 WSO2 EI documentation [1] explains how to achieve it.
WSO2 EI文档[1]解释了如何实现。 If you scroll down the documentation you will find an example in which they have used XPath in expression of iterate mediator.
如果向下滚动文档,您将找到一个示例,其中他们在迭代中介器的表达式中使用了XPath。
If you specifically want to have a property because there is a change in the body. 如果您特别想拥有一个属性,因为身体有所变化。 You can preserve the body on which you want to iterate in a property and apply the value of that property to body right before the iterate mediator and then directly use XPath to iterate the body.
您可以在属性中保留要在其上进行迭代的主体,并在迭代中介器之前将该属性的值应用于主体,然后直接使用XPath来迭代主体。
