How to make a dynamic xPath and execute it? - properties

Question

I collect string to xpath
<property xmlns:t="https://services" name="xPathElemet" expression="fn:concat(//t:SNILS/, $func:element)"/>
and I want to run this xpath and write the value of a Property
<property name="KEY" expression="get-property('xPathElemet')"/>
but receive only collected a string
how to xpath of the Property?
example code sequence :
<iterate continueParent="true" expression="//t:Employee">
<target>
<sequence>
<call-template target="save_element">
<with-param name="key_element" value="Name"/>
</call-template>
</sequence>
</target>
</iterate>
example code template :
<template xmlns="http://ws.apache.org/ns/synapse" name="save_element">
<parameter name="key_element"/> <!--example: "Name"-->
<sequence>
<property name="KEY" expression="fn:concat(//t:Employee/t:SNILS, ':' ,$func:key_element)" scope="default"
type="STRING"/> <!--example: "111-111-111-1:Name"-->
<property name="xPathElemet" expression="fn:concat('//t:Employee/t:', $func:element)"/> <!--example: "//t:Employee/t:Name"-->
<property name="VALUE" expression="get-property('xPathElemet')" scope="default" type="STRING"/> <!--example: Den (Now it does not work)-->
<dbreport>
<connection>
<pool>
<seetings/>
</pool>
</connection>
<statement>
<sql>
<![CDATA[insert into cache( key , value ) values (?, ?);]]></sql> <!--insert new line where key = "111-111-111-1:Name" and value = "Den"-->
<parameter expression="get-property('KEY')" type="VARCHAR"/>
<parameter expression="get-property('VALUE')" type="VARCHAR"/>
</statement>
</dbreport>
</sequence>
</template>
example xml:
<Employees xmlns="https://services">
<Employee>
<SNILS>111-111-111-1</SNILS>
<Name>Den</Name>
</Employee>
<Employee>
<SNILS>111-111-111-2</SNILS>
<Name>Elena</Name>
</Employee>
</Employees>

Answer 1

Use evaluate
In your case:
<property xmlns:t="https://services" name="xPathElemet" expression="fn:concat(//t:SNILS/, $func:element)"/>
<property name="KEY" expression="evaluate(get-property('xPathElemet'))"/>
You can find more infomation in this blog.

Answer 2

Please try the following and see if it works
<property xmlns:t="https://services" name="xPathElemet" expression="fn:concat(//t:SNILS/, $func:element)"/>
<property xmlns:t="https://services" name="xPathfull" expression="fn:concat(get-property('xPathElemet'),'/text()')"/>
<property name="KEY" expression="get-property('xPathfull')"/>
What was missing from your code was the /text() which refer to the parameters of the given xpath. Please try this
