In Groovy, how do I get the value in an element with a specific attribute in XML -


i have groovy script compares xml response jdbc query. trying account scenario need validate xml value based on specific attribute in element.

here example of xml:

               <forminstance id="impairment_0111235228_2_174_477">               <formname>new medical history note</formname>               <providerformnumber>174</providerformnumber>               <formresponse id="imapairment_477_6">                  <questionnumber>477</questionnumber>                  <questiontext>examone rx</questiontext>                  <answerchoice>                     <answerchoicetext>examone result</answerchoicetext>                     <olifeextension vendorcode="08" extensioncode="impairmentattributetype">lbl</olifeextension>                     <olifeextension vendorcode="08" extensioncode="impairmentattributeseq">2</olifeextension>                  </answerchoice>                  <olifeextension vendorcode="08" extensioncode="impairmentsequence">1</olifeextension>                  <olifeextension vendorcode="08" extensioncode="questionsequence">6</olifeextension>               </formresponse>            </forminstance>

as can see, there several elements name "olifeextension", unique extensioncode attributes. need able compare value attribute. example, using xml above, if attribute extensioncode = questionsequence, expect see value of 6.

i have tried following in script:

    obj.questionsequence = xml.formresponse.olifeextension.{'@extensioncode' == 'questionsequence'}      obj.questionsequence = xml.formresponse.{it.name() == 'olifeextension' && it.@extensioncode == 'questionsequence'}      obj.questionsequence = xml.formresponse.olifeextension.{it.@extensioncode == 'questionsequence'}

the syntax on 3 examples appear correct because don't errors when run script, when output results, empty.

i tried:

obj.questionsequence = xml.formresponse.olifeextension[1]

this works, problem here questionsequence may not exist in same spot. position 0 or 2. so, need work off attribute name.

also, base of script using in response question if needed anyone.

compare jdbc response xml response number of nodes vary , order change?

thank in advance help.

of course, right after ask question, figure out. if has cleaner way it, appreciate it, seems trick.

obj.questionsequence = xml.formresponse.olifeextension.find{it.@extensioncode == 'questionsequence'}
