Locating XML Element - Predicate

[Jazzmanflynn]

Hello,

I am trying to bind a text field in Designer 8.1 to a specific XML element.

An example of the XML structure:

<KeyValueGroup>

     <ID>

          <Name>Name1</Name>

          <Value>Value1</Value>

     </ID>]

     <ID>

          <Name>Name2</Name>

          <Value>Value2</Value>

     </ID>

     <ID>

          <Name>Name3</Name>

          <Value>Value3</Value>

     </ID>

</KeyValueGroup>

I have been trying to bind using $record.KeyValueGroup.ID[Name="Name2"].Value to return the value of the Name2 property, however Designer rejects this expression.

Would anyone be able to advise where I am going wrong?

I understand I could achieve this using a Javascript function that enumerates the ID array, but would prefer to find a solution not involving javascript if possible.

Any help much appreciated,

Matt

Hi Matt,

The $record refers to the current subtree of the Data DOM, so in your case $data.KeyValueGroup and $record are the same thing.

You also need a "." before the predicate.

Anyway, try  $record.ID.[Name=="Name2"].Value

Good Luck

Many thanks Bruce!

Your solution worked perfectly and I have learnt something in the process!

It makes so much sense to have the "." before the predicate but it was something that never occurred to me!

Have a wonderful day,

Matt
