stm:set

The stm:set operation is used to set the value of elements or attributes. It does not create or modify document structure it cannot be used to create or rename elements. The value to be set is obtained from the select xpath location of the enclosed fragment.

Example

Example 1: Set This example sets /a/b[1]/c, whose initial value is horse, to the value zebra from the /x/y element enclosed by the stm:set operation. <idoc>   <seq>     <instr>       <type>stm</type>       <operand>var:vardoc.xml</operand>       <operator>         <stm:group xmlns:stm="http://1060.org/stm">           <stm:set select="/x/y" xpath="/a/b[1]/c">             <x>               <y>zebra</y>             </x>           </stm:set>         </stm:group>       </operator>       <target>this:response</target>     </instr>   </seq> </idoc> Try it

Example 2: Set with value from Param In this example we introduce param substitution. Any element named <stm:param> within an stm operation element is substituted by the document fragment from the parameter document at the location given by the <stm:param> xpath attribute. As is always the case for any URA the param document is passed to the stm operation by the <param> element of the idoc instruction. In detail, this example sets the value of /a/[b]/c to the value at /i/j[1]/k that is it sets horse to haddock! <idoc>   <seq>     <instr>       <type>stm</type>       <operand>vardoc.xml</operand>       <operator>         <stm:group xmlns:stm="http://1060.org/stm">           <stm:set select="/i/j[1]/k" xpath="/a/b[1]/c">             <stm:param xpath="/*" />           </stm:set>         </stm:group>       </operator>       <param>varparam.xml</param>       <target>this:response</target>     </instr>   </seq> </idoc> Try it

Example 3: Set an Attribute Value In this example we set an attribute value. <idoc>   <seq>     <instr>       <type>stm</type>       <operand>doc.xml</operand>       <operator>         <stm:group xmlns:stm="http://1060.org/stm">           <stm:set select="/food" xpath="/a/b[1]/c/@food">             <food>biscuits</food>           </stm:set>         </stm:group>       </operator>       <target>this:response</target>     </instr>   </seq> </idoc> Try it
