SQL Server and xml -

-

i pass xml varchar scalar function in sql server:

<screenerinfo>     <extendexpiryinfo>         <extendexpiry>             <actionon>2015-05-19 13:31:40.019</actionon>             <comments>nikilesh</comments>             <approvalstatus>ee</approvalstatus>             <newexpirydate>2015/06/25 12:28:59pm</newexpirydate>         </extendexpiry>     </extendexpiryinfo> </screenerinfo>

i want retrieve every thing between comment tag , separate each comment comma store in varchar variable , return how can achieve this......

for eg...

nikilesh,manish,done,rejected...

how possible?

i don't know, "manish" or "done" or "rejected" comes from, asking content of comments-node i'd assume, there more nodes these phrases in comments-node. in following example copied example node 3 times , changed content of comments. if paste empty query window you'll get: 

result: nikilesh, manish, done  declare @xml xml= '<root>   <screenerinfo>     <extendexpiryinfo>         <extendexpiry>             <actionon>2015-05-19 13:31:40.019</actionon>             <comments>nikilesh</comments>             <approvalstatus>ee</approvalstatus>             <newexpirydate>2015/06/25 12:28:59pm</newexpirydate>         </extendexpiry>     </extendexpiryinfo>   </screenerinfo>   <screenerinfo>     <extendexpiryinfo>         <extendexpiry>             <actionon>2015-05-19 13:31:40.019</actionon>             <comments>manish</comments>             <approvalstatus>ee</approvalstatus>             <newexpirydate>2015/06/25 12:28:59pm</newexpirydate>         </extendexpiry>     </extendexpiryinfo>   </screenerinfo>   <screenerinfo>     <extendexpiryinfo>         <extendexpiry>             <actionon>2015-05-19 13:31:40.019</actionon>             <comments>done</comments>             <approvalstatus>ee</approvalstatus>             <newexpirydate>2015/06/25 12:28:59pm</newexpirydate>         </extendexpiry>     </extendexpiryinfo>   </screenerinfo> </root>';   select stuff( (     select ', ' + screener.info.value('(extendexpiryinfo/extendexpiry/comments)[1]','varchar(max)')     @xml.nodes('/root/screenerinfo') screener(info)     xml path('') ),1,2,'')
