xml - plsql updatexml- can't update value based on attribute -


i'm working database oracle 11g, , has xml fields like:

<bookstore id="other">     <fractionofbooks>1.0</fractionofbooks> </bookstore> <bookstore id="main">     <fractionofbooks>0.0</fractionofbooks> </bookstore> <bookstore id="small">     <fractionofbooks>0.0</fractionofbooks> </bookstore>

so need change fraction id="other" 0.0, , id="main" 1.0.

i'm doing 2 queries, first do:

update   db.mytable set   xml = updatexml(                 xml,                 '/*:bookstore/[@name="other"]/*:fractionofbooks',                 0.0   )

oddly, if select record, resulting xml has missing last tag, becomes:

<bookstore id="other">0</bookstore> <bookstore id="main">     <fractionofbooks>0.0</fractionofbooks> </bookstore> <bookstore id="small">     <fractionofbooks>0.0</fractionofbooks> </bookstore>

i don't think it's nice solution set value including tag, can me figure out wrong?

thanks

i miss text() function after last node: updating node instead of contents. see:
