With ACL, Error when i try to evaluate an XPath expression with the function "oid_xpath_nodeset"

[dgopois]

Hello,

With ACL, I try to use this function:

oid_xpath_nodeset(oid_root(), arr, "count(//proceduralStep)>0");

The function fails with the error message:

[A30283] Cannot convert result to requested type: Cannot convert 'number' to 'string'

However, the following function executes successfully:

oid_xpath_boolean(oid_root(),"count(//proceduralStep)>0")

Can you help me to solve this problem ?

Hello,

My explanation to the problem:

• Evaluating this expression ""count(//proceduralStep)" returns a number
• Evaluating this expression ""count(//proceduralStep)>0" returns a boolean
• Evaluating this expression ""//proceduralStep" returns a string

The function "oid_xpath_nodeset" must evaluate an expression which returns a result of type string

Regards
