XPATH Select All Attributes attr Except One On Specific Element elem

I was selecting all attributes id and everything was going nicely then one day requirements changed and now I have to select all except one!

Given the following example: 

<root> 
  <structs id="123"> 
    <struct> 
      <comp> 
        <data id="asd"/> 
      </comp> 
    </struct> 
  </structs> 
</root>

I want to select all attributes id except the one at /root/structs/struct/comp/data

Please note that the Xml could be different. Meaning, what I really want is: given any Xml tree, I want to select all attributes id except the one on element /root/structs/struct/comp/data

I tried the following:

//@id[not(ancestor::struct)] It kinda worked but I want to provide a full xpath to the ancestor axis which I couldn't

//@id[not(contains(name(), 'data'))] It didn't work because name selector returns the name of the underlying node which is the attribute not its parent element

The following should achieve what you're describing:

//@id[not(parent::data/parent::comp/parent::struct/parent::structs/parent::root)]

As you can see, it simply checks from bottom to top whether the id attribute's parent matches the path root/structs/struct/comp/data.

I think this should be sufficient for your needs, but it does not 100% ensure that the parent is at the path /root/structs/struct/comp/data because it could be, for example, at the path /someOtherHigherRoot/root/structs/struct/comp/data. I'm guessing that's not a possible scenario in your XML structure, but if you had to check for that, you could do this:

//@id[not(parent::data/parent::comp/parent::struct/parent::structs/parent::root[not(parent::*)])]
