How to output <field/> instead of <field></field>?

[Former Member]

Hi Experts,

When outputting XML files, the file receiver adapter would parse blank or null values like this:

<field></field>.

But a 3rd part system does not support this format(really weird, but it's true), it only supports:

<field/>.

Is there any way to control the file receiver adapter to output blank/null nodes as <field/> but not <field></field>?

Any advice is appreciated, thanks a lot for you your.

Best regards

Hi Luis,

Does the Sender XML message in XI have the corresponding node? It looks like this node itself is absent, as against the node existing with a blank value.

If this is the case, in the node mapping, you may have to use the 'Exists' function in conjunction with a 'IfWithoutElse' function.

I had same problem with my one scenario, i use IfWithoutElse & compare with null constant.

Then if node is coming null then it won’t come in o/p xml.

Hope this helps,

Hi friends,

I've got a solution for this issue: Use Java Mapping.

In my Java mapping method execute(), I set the property of the output as "Indent". In this case, null nodes will output as <field/>.

This is obviously a poor solution, but it really works. Thanks for all your kind help.

Hi Luis,

Interesting. I had used a file receiver which outputs an XML document with blank fields like <field />

Check in the mapping if value exists otherwise try to map it with a constant having blank value

Otherwise try changing the occurence of the element (if you have 1 then change to 0 and check)

Hi,

Map the nodes with <b>mapwithdefualt</b> and give the default value or some spaces if it is allowed.

Else if the target node is having the occurrences as 0..unbound then exists - createif map to node.

Else if your requirement should give the result as <field/> if the value is not existed then i hope better to go for Java mapping or other or write Adapter module.

to write adapter module see below link.

No, this is not possible.

You have to write an adapter module to achieve this.

I have seen that XSLT mapping creates <field /> as well. Maybe you can go for XSLT in your scenario.
