I have the code below which uses the attached .csv file as an input; my problem comes at the _null_ datastep.

 

I am trying to create a .xml file which holds the dataseries from all three states, but I can only get the last one. Ideally, my output would look smth like this. What am I doing wrong? Note value1 is different across state series.

 

Any thoughts would be extremely appreciated; thanks in advance.

 

<path> AL value1 value2................................................................................valueN </path>

<path> AR value1 value2...............................................................................valueN </path>

<path> AK value1 value2...............................................................................valueN </path>

 

data hpi;
 infile "FilePath\DataRaw.csv" dsd firstobs=2;
 length Date $6; 
 input Date $ AL AR AK;
run;

data newdata;
  set hpi;
   x=indexc(Date,'-');
   if x=3 then do;
     year=compress(substr(Date,1,2));
     month=compress(substr(Date,4,6));
   end;
   if x=4 then do;
     year=compress(substr(Date,5,6));
     month=compress(substr(Date,1,3));
   end; 
   year='20'||year;
   newDate=compress(cat(month,year));
   newDate2=input(newDate,monyy7.);
   format newDate2 monyy7.;
   keep AK AL AR newDate2;
   rename newDate2=Date;
run;

                out=newdata1;

I have simplified last step using array and a do loop:

data _null_;
  file "&FilePath.HPA.xml";
  set newdata1 end=last;
     array dat _numeric_;
     if _N_=1 then PUT @001 '<?xml version="1.0"?>';
   
     PUT @1 '<path>' state @;
     do i=1 to dim(dat);
       put dat(i) @;
     end; 
     PUT '</path>';
run;

I have tried several changes to the xml line format but unsuccefully.

With that last code I get the next message:

"error on line 3 at column 1: extra content at the end of the document".

The error I get is on my linux system.

I opened the file in win10 system and no errors - all 3 states exist.

Attached is the HPA_xml.txt file. Rename it to HPA.xml and try to open it on your system.

I'm looking at your code and it is not clear:

data _null_;
  file "FilePath\HPA.xml";
  set newdata2 end=last;
   /*PUT @001 '<?xml version="1.0"?>' */
   do _n_=1 to last;
     PUT @001 '<path>' /
      state DEC2016 JAN2017 FEB2017 MAR2017 ...
     .............
.............
' </path> '; end; output; run;

- what did you mean by do _n_=1 to last; ...end ?  You can cancel the do - end statement,

 as the SET statement makes this loop implicitly.

- there is no meaning to the output statement when you start with data _null_;

  You write to the file using put statement.

Understood; your point is very well taken. I have deleted the loop and I am now using PGStats' code below; the problem now is that I am only getting the AL record; I am missing the AR and AK records. Thoughts?

Could be simplified to:

 

data hpi;
 infile "&sasforum\datasets\DataRaw.csv" dsd firstobs=2;
 length DateStr $6; 
 input DateStr AL AR AK;
 yr = compress(DateStr,,"kdo");
 mt = compress(DateStr,"-","do");
 date = input(cats("01",mt,"20",yr),date9.);
 format date yymm.;
 keep date al ar ak;
run;

proc transpose data=hpi out=newData name=State prefix=d_;
var al ar ak;
id date;
run;

data _null_;
  file "&sasforum\datasets\HPA.xml";
  set newdata;
  if _n_=1 then PUT '<?xml version="1.0"?>';
  PUT '<path>' / State (d_:) (best8.2) / '</path>';
run;

Thanks for getting back to me; I used your code. The problem now, however, is that I am getting only the AL record; I am missing the AK and AR records in my output .xml file.Thoughts?

I ran your code adapted to my SAS UE environment with the changes I popsted before, that is:

data _null_;
  file "FilePath\HPA.xml";
  set newdata2 end=last;
   if _N_=1 then PUT @001 '<?xml version="1.0"?>';
   do _n_=1 to last;
     PUT @001 '<path>' /
      state DEC2016 JAN2017 FEB2017 MAR2017 ...
     .............     .............    
/'</path>'; end; run;

When I opened the HPA.xml created file I see only AL BUT

1) There is an error message: "error on line 5 at column 1: Extra content at the end of the document"

2) When I asked to view the source there ar all 3 states.

 

So the error is a XML format error and not SAS programming error.

 

BTW - in your first step, better change next lines to avoid warning messages in the log:

   if x=3 then do;
     year=compress(substr(Date,1,2));
     month=compress(substr(Date,4,3));
   end;
   if x=4 then do;
     year=compress(substr(Date,5,2));
     month=compress(substr(Date,1,3));
   end;

Thanks. Any ideas on how to deal with this .xml formatting error?
