import xml file into sas

Alexxxxxxx — Sat, 22 May 2021 15:02:27 GMT

Hello all,

May I ask how to import a series of XML files into SAS (the attached is a sample of the XML file)?

I have tried the two method and got the following results,

first method

filename xx temp;
libname xx xmlv2 'F:\USPTOPatentExaminationDataSystem/1960.xml' automap=replace xmlmap=xx;
proc copy in=xx out=xx;
run;

Result
1    filename xx temp;
2    libname xx xmlv2 'F:\USPTOPatentExaminationDataSystem/1960.xml' automap=replace xmlmap=xx;
ERROR: The creation of the XML Mapper file failed.
ERROR: Error in the LIBNAME statement.
3    proc copy in=xx out=xx;
NOTE: Writing HTML Body file: sashtml.htm
4    run;

ERROR: Libref XX is not assigned.
NOTE: Statements not processed because of errors noted above.
NOTE: PROCEDURE COPY used (Total process time):
      real time           0.38 seconds
      cpu time            0.28 seconds

NOTE: The SAS System stopped processing this step because of errors.
NOTE: Parsing with high validation.

second method

libname myxml xml 'F:\USPTOPatentExaminationDataSystem\1960-1979-pairbulk-full-20201213-xml\1960.xml';
libname dat 'I:\Data_in_SAS\USPTO';
data dat.subjects;
 set myxml.subjects;
run;
proc print data = dat.subjects noobs;
run;

result

Could you please give me some advice about this? Many thanks in advance.

Couldn't you simply pre-process the file to change the string "RegisteredPractitionerRegistrationNumber" ?

That means your XML file is not correct .

What do you want to see FROM this xml ?

Post the table you want to get that would be better .

filename x'c:\temp\1960.xml' termstr=lf;
data have;
infile x truncover length=len;
input have $varying2000. len;
if strip(have) =: '<uscom:ApplicationNumberText' then group+1;
want=prxchange('s/\<.+?\>//',-1,have);
if not missing(want);
run;

proc transpose data=have out=want;
by group;
var want;
run;
