[xml] adjusting the indent level

[Aaron Patterson <aaron patterson gmail com>]

Hi,

Is there a way to adjust the indenting level when using xmlSaveToIO()?
 I've set xmlIndentTreeOutput to 1, set the xmlTreeIndentString, and
made sure to enable XML_SAVE_FORMAT in the options, but none of this
seems to help.  Any hints would be greatly appreciated.

The code I have right now is like this:

  xmlIndentTreeOutput = 1;
  xmlTreeIndentString = "---------------";

  xmlSaveCtxtPtr savectx = xmlSaveToIO(
      (xmlOutputWriteCallback)io_write_callback,
      (xmlOutputCloseCallback)io_close_callback,
      (void *)io,
      NULL,
      options
  );

  xmlSaveTree(savectx, node);
  xmlSaveClose(savectx);

Thank you!
