Symbol outline / search: Customizable display text

[photasm]

It would be nice to have the option to customize how symbol outline / search will be displayed.
This could be done by using the attribute on the displayed element.

<Element1>
  <Element2 id="id1" />
   <Element2 id="id2" />
   <Element2 id="id3" />
</Element1>

In my case my symbol outline looks like this:

Element1
--Element2
--Element2
--Element2

It would be nice, if it could look sth like this:

Element1
--Element2 (id1)
--Element2 (id2)
--Element2 (id3)

Thx. :)

@photasm indeed it should be nice. The main reason why we have not implemented that is that when XML is too big, outline crashes the vscode.

But since we have added a symbol settings to disable it, I think it's a good idea to add a new settings to add attributes in the outline.

Great, thank you in advance.

I would like to expand on that. There should be several attributes to configure, which get tested for in sequence.

@id, @title, @name, @class are good candidates. If none of them is available, the start of the text node could be shown.

I did a quick POC for this issue.

Given the test.xml XML file:

<Element1>
  <Element2 id="id1" />
   <Element2 id="id2" />
   <Element2 id="id3" name="name3"/>
   <Element2>ABCD</Element2>
</Element1>

we want to show :

• all text node (ABCD in this case)
• only @id attribute (not @name)

To manage this configuration, I introduce a new settings xml.symbols.filters:

 "xml.symbols.filters": [
      {
         "pattern": "test.xml",
         "expressions" :[
            {
               "xpath": "//text()",
               "excluded": false
            },
            {
               "xpath": "//@id",
               "excluded": false
            }
         ]
      }
   ]

• pattern means that filters are apply only for file name which match the pattern.
• expressions are a list of xpath node to include or exclude.

Any feedback are welcome!
