Mmm, its odd that the wildcard doesn't work. Anyways, just change to:
%macro imp_xml (fname=,mapname=);
/* This is your original code, I have just replaced the file and map name as parameters */
filename datafile 'h:\Practice\PARI\&fname.';
filename mapfile 'h:\Practice\PARI\XML\&mapname.';
libname datafile xmlv2 xmlmap=mapfile automap=replace;
proc copy in=datafile out=work;
run;
filename datafile clear;
filename mapfile clear;
libname datafile clear;
%mend imp_xml;
/* Clean work so that we can append all datasets created */
proc datasets lib=work memtype=data kill nolist;
run;
/* This is a pipe from your Operating system, it is the same as doing a directory listing
from the command prompt. It will feedback all the filenames with the extension xml
in the folder given */
filename inlist pipe 'dir "h:/Practice/PARI" /b';
/* I replace the _null_ part here, you can look at dirlist dataset in work to see what is read
in from the directory listing */
data dirlist;
length buff mfile $200;
infile inlist;
input buff $;
mfile=tranwrd(lowcase(buff),".xml",".map");
/* The next step creates one macro call for every filename returned by the directory listing
from the command prompt */
call execute(cats('%macro imp_xml (fname=',buff,',
mapname=',mfile,');'));
run;
filename inlist clear;
/* Combine all the datasets in work */
data _null_;
set sashelp.vtable (where=(libname="WORK"));
/* These next steps will generate firstly one dataset called want, then from there on in
one proc append for every dataset in the work library */
if _n_=1 then call execute(cats('data want; set ',strip(memname),';run;'));
else call execute(cats('proc append base=want append=',strip(memname),' force;run;'));
run;
/* Remove all files except the final one */
proc datasets lib=work memtype=data kill nolist;
save want;
run;
So just take the /*.xml
Off the pipe and it should list all the files in that directory.
