Missing labels and empty folder tags

Most likely you have a RAM disk associated with an image file. In this case a disk label or folders will not be exported in XML because this information is stored in the image file and is not a part of the disk configuration.

For a regular volatile RAM disk, it should work flawlessly and exactly as you expect. For example, this configuration:

Becomes the following XML:

<?xml version="1.0" encoding="UTF-8"?>
<ramdisk>
  <mount/>
  <boot>
    <item>
      <image>
        <filename></filename>
      </image>
      <folders>
        <name>Documents</name>
        <name>Downloads</name>
        <name>Cache</name>
        <name>Temp</name>
      </folders>
      <filesystem>4</filesystem>
      <size>32768</size>
      <savetoimage>False</savetoimage>
      <autoflush>False</autoflush>
      <flushtime>0</flushtime>
      <clustersize>0</clustersize>
      <letter>Z</letter>
      <removable>False</removable>
      <label>RAM</label> 
      <compressed>False</compressed>
      <hddemulation>False</hddemulation>
      <numanode>0</numanode>
      <specnuma>False</specnuma>
    </item>
  </boot>
</ramdisk>

Sorry I am a little confused with what you are trying to achieve. The XML files are used to transfer a RAM disk configuration from one computer to another. There is really no point in having "copy" commands in it.

If you want to copy some files to a volatile RAM disk upon login, this can be done via Tools - Applications - Add. The RAM Disk app will execute all programs listed there when all RAM disks are mounted. Say, you could create a batch file that copies all files you need to a RAM disk and have it launched by the RAM Disk app once all RAM disks are ready.

If you are trying to achieve something else, please let me know and I will recommend the best way to do it.
