diff --git a/docs/cps-path.rst b/docs/cps-path.rst index e8a75d9cf0..fba21f38c6 100644 --- a/docs/cps-path.rst +++ b/docs/cps-path.rst @@ -234,12 +234,15 @@ leaf-conditions - ``//categories[@name="Kids"]`` - ``//categories[@name='Kids']`` - ``//categories[@code='1']/books/book[@title='Dune' and @price=5]`` - + - ``//categories[@code=1]`` **Limitations** - Only the last list or container can be queried leaf values. Any ancestor list will have to be referenced by its key name-value pair(s). - Multiple attributes can only be combined using ``and``. ``or`` and bracketing is not supported. - Only leaves can be used, leaf-list are not supported. - Only string and integer values are supported, boolean and float values are not supported. + - The key should be supplied with correct data type for it to be queried from DB. In the last example above the attribute code is of type + Integer so the cps query will not work if the value is passed as string. + eg: ``//categories[@code="1"]`` or ``//categories[@code='1']`` will not work because the key attribute code is treated a string. **Notes** - For performance reasons it does not make sense to query using key leaf as attribute. If the key value is known it is better to execute a get request with the complete xpath. |
