Restricting XML Elements Based on Another Element via XSD

by

Similar questions have been asked several times .. in stackoverflow or any tech blogs ..

but the answer is always not possible,

cases like :

(a) validating Element depending on the value or presence of any other element/attribute
(b) validating value of an element depending on the value or presence of any other element/attribute
(c) validating attribute depending on the value or presence of any other element/attribute
(d) defining elements/attributes of same name having different Types/DataTypes under same scope
(e) validating child elements on the basis of value or presence of any other Elements/Attributes

all the above mentioned cases are not possible to achieve ..

but if you can implement some transformation thing .. then you can get help.
what I mean to say is “first go through transformation and modify the XML as per your requirement,

example :: if the particular field is expected with some value .. pass the XML as it is if the condition is satisfied and don’t pass if it doesn’t ..
in the next block XSD is going to validate and obviously errors out 🙂 you can figure out that it is missing your custom validation ..

anyway the intention is to block or Pass the xml according to the data .. and that is what you are doing ..
