Allow currently processed/parsed URL to be read from data parser plugin

Here is the proposed patch introducing the new setter method

Minor changes to issue title and body

Here is an improved patch that also gets the URL for the first item.

Here is a slightly updated patch that fixes Only variables should be passed by reference warnings due to the array_shift(array_keys($this->urls)) part.

Tests will be added soon (if I can get them to run, hehe).

...and here comes a new patch with a current URL test added to the simple_xml parser kernel test. I chose this one, because it has a better setup compared to json parser kernel test and allows reusing its basic configuration.

Removing the "Needs tests" tag, as there is a test contained in the last submitted patch

Any news on this? Would really like to see this getting into the module.

Anybody?! ;)

@timilie: Sorry for the late reply. In my case, I needed this for a custom data parser plugin that is used when reading multiple XML files from a directory. In order to e.g. be able to use the basename of the currently parsed/read file as an identifier, I needed this new functionality. In my custom data parser I do the following:

protected function fetchNextRow() {
  parent::fetchNextRow();

  // Inject file metadata.
  if ($this->valid()) {
    $current_file_url = $this->currentUrl();
    $this->currentItem['my_custom_source_prop'] = basename($current_file_url);
  }
}

With this, I can access the basename value via my_custom_source_prop source property in each row.

Hope this helps?

Any news on this or is there still something to do to get it in?! I'd appreciate your feedback

@Matroskeen No worries, but of course I am still interested in getting this in ;) I had a quick look at your comments and I'll take some time to fix all the stuff later today. Thanks for the feedback

So all issues should be resolved. I guess I used the wrong buttons when commenting in the MR, but I hope you can get through my changes ;)

The last open thread should be resolved... but I don't find any button how to resolve this from my end ;) But setting this to RTBC for now.
