Hi There,
I have a requirement to count the number of elements in the incoming message. The trick part is i need to find the name of the element first.
For example. In the below xml message, i have a complex element by name Employees, three simple elements, Where each element name is Employee3, the Number 3 in the element is because there are three Employee3 in the incoming message.
Sample.xml
<Company>
<Employees>
<Employee3>010101</Employee3>
<Employee3>010102</Employee3>
<Employee3>010103</Employee3>
</Employees>
</Company>
Now the requirement is to find the count of Employee3 in this case the count is 3, But in general Number 3 is variable. it can go from 1 to N.
The question is how to find count of EmployeeN, any input is helpful.
[/i]

You can find the name of the first child of <Employees> using the fieldname function.
This allows you to cater for a different tag name.
Then the cardinality function may help getting the count of the number.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

| Code: |
DECLARE aName CHARACTER FIELDNAME(InputBody.Company.Employees.*[>]);
DECLARE aCount CHARACTER CARDINALITY(InputBody.Company.Employees.*[]); |
Something like that? Assuming that all children of <Employees> have the same fieldname, of course. |

It is not a good idea to write the code for someone else. Just give him/her the clues and let them try for themselves. Or are they getting paid for you to code their ESQL ? |

Probably not. But I feel bad about just swearing at people and telling them to RTFM. After all, I've asked my share of stupid questions too, and I appreciated the help I got from the people here. |

Hi smdavies99 and Gralgrathor,
Thank for the response guys, i really appreciate it.
I can't take go by your suggestion, i should have put my question correct at first place, in my sample xml, there are so many other elements, but i am interested in count of <EmployeeN>, that make little hard to find out.
<Company>
<Employees>
<team>sap</team>
...etc
<Employee3>010101</Employee3>
<Employee3>010102</Employee3>
<Employee3>010103</Employee3>
</Employees>
</Company>

Then look at the code I posted. It'll give you the name of the first element of the list and the number of siblings. |

I think it is time to ask an important question.
Why do you need to know the count?

More importantly, who in his right mind would design an XML schema in which the number of elements is encoded into the field name? Isn't that, like, insane? |
