Are you asking if there is a way in your map file to specify that when you use it to convert an XML file to a SAS dataset that the name of the XML being converted? I would be very surprised if that is possible as why would the map file know anything about the source of the file that it is being used to parse?   You could do that in separate logic.  Let's setup an example by creating an XML file. libname out xmlv2 'c:\downloads\class1.xml'; data out.class; set sashelp.class; run; libname out clear; Now let's read that back into a SAS dataset and use the PATHNAME() function to find the path that the libref being used. libname in xmlv2 'c:\downloads\class1.xml'; data class; set in.class ; filename=pathname('in'); run; Results: Obs Name Sex Age Height Weight filename 1 Alfred M 14 69 112.5 c:\downloads\class1.xml 2 Alice F 13 56.5 84 c:\downloads\class1.xml 3 Barbara F 13 65.3 98 c:\downloads\class1.xml 4 Carol F 14 62.8 102.5 c:\downloads\class1.xml 5 Henry M 14 63.5 102.5 c:\downloads\class1.xml 6 James M 12 57.3 83 c:\downloads\class1.xml 7 Jane F 12 59.8 84.5 c:\downloads\class1.xml 8 Janet F 15 62.5 112.5 c:\downloads\class1.xml 9 Jeffrey M 13 62.5 84 c:\downloads\class1.xml 10 John M 12 59 99.5 c:\downloads\class1.xml 11 Joyce F 11 51.3 50.5 c:\downloads\class1.xml 12 Judy F 14 64.3 90 c:\downloads\class1.xml 13 Louise F 12 56.3 77 c:\downloads\class1.xml 14 Mary F 15 66.5 112 c:\downloads\class1.xml 15 Philip M 16 72 150 c:\downloads\class1.xml 16 Robert M 12 64.8 128 c:\downloads\class1.xml 17 Ronald M 15 67 133 c:\downloads\class1.xml 18 Thomas M 11 57.5 85 c:\downloads\class1.xml 19 William M 15 66.5 112 c:\downloads\class1.xml   ...

The documentation page is here. I read this sentence as: The TABLE element can contain one instance of each of the following elements: TABLE-PATH, TABLE-END-PATH, TABLE-DESCRIPTION, and COLUMN. Your lexical interpretation is valid too, though I don't see how it would work. Best to ask Tech Support to clarify. ... View more

_INFILE_ is a variable. So is limited by the same rules as any other variable.   When posting code or log entries copied from your editor or SAS log it works best on the forum to open a code box using either the {I} or "running man" icon at the top of the message window. That will prevent the forum software from reformatting text. So you get something like: DATA TOC1 ; INFILE RECIN LRECL = 1000000; LENGTH UNQ_KEY $18. RETVER $20.; INPUT @(INDEX(_INFILE_,'')+17) UNQ_KEY $CHAR18. @(INDEX(_INFILE_,'Version=')+15) RETVER $CHAR20. ; IF FIND(RETVER, '"') > 0 THEN RETVER=SUBSTR(RETVER,1,(FIND(RETVER,'"')-1)); NUM_DOCS=COUNT(_INFILE_,' documentId=') ; TEST_LENGTH= LENGTH(_INFILE_); RUN; (If that is close to what your code looked like in the editor). The two code boxes do things slightly differently. The {} is pretty much plain text while the "running man" will attempt to use some syntax highlighting rules. ... View more
