[1] You should use XXE.edit rather than XXE.open. Unlike XXE.open,
XXE.edit will simply switch to the file if it is already opened in XXE.
See http://www.xmlmind.com/xmleditor/_distrib/doc/commands/XXE.edit.html
[2] You need to pass an absolute URL to XXE.edit (or XXE.open).
In order to convert a relative URL to an absolute one, you need:
[a] to use xpath() instead of attr(). See
http://www.xmlmind.com/xmleditor/_distrib/doc/csssupport/xpath.html
[b] to use XPath extension function
---
string resolve-uri(string uri, ?string base?)
---
See http://www.xmlmind.com/xmleditor/_distrib/doc/commands/xpathextfunc.html
I've not tested this but:
---
@property-value open-file()
command-button(text, "OpenFile",
icon, square,
command, "XXE.open",
parameter, xpath("resolve-uri(@href)"));
---
should work fine.

PS: The DITA toolbar already has a button which does exactly what you want.
