Now you could add phpi_get_le_*() calls to the xmlnode extension but this causes problems when one is configured as a shared library and the other as statically build into PHP. Your best bet is probably to use the new Zend API call ZEND_GET_RESOURCE_TYPE_ID(<resource_name>) (Please note this will not be in any PHP distribution until 4.0.7). This will return the resource type id of the resource type with the name <resource_name> which you can then use it as the second value to the ZEND_REGISTER_RESOURCE macro (and any other calls that require this value :)). See pdf.c and cpdf.c for example usage (grep for le_gd) and zend_list.h for the implementation of the macro. The return value should be "cached" locally as this call requires iterating though a hash table which isnt that fast :) HTH, - James
