I have a data set in an XML file with a format similar to the sample below.

 

<?xml version="1.0" encoding="UTF-8"?>
<PEOPLE xmlns:HOME="http://sample.url.org/home"
xmlns:IP="http://sample.url.org/ip"
xmlns:WORK="http://sample.url.org/work">
<PERSON>
<NAME>Joe Smith</NAME>
<HOME:ADDRESS>1234 Elm Street</HOME:ADDRESS>
<HOME:PHONE>999-555-0011</HOME:PHONE>
<WORK:ADDRESS>2001 Office Drive, Box 101</WORK:ADDRESS>
<WORK:PHONE>999-555-0101</WORK:PHONE>
<IP:ADDRESS>192.168.1.1</IP:ADDRESS>
</PERSON>

<PERSON>

<HOME:PHONE>999-555-0033</HOME:PHONE>
<WORK:ADDRESS>2001 Office Drive, Box 103</WORK:ADDRESS>
<WORK:PHONE>999-555-0103</WORK:PHONE>
<IP:ADDRESS>10.0.1.1</IP:ADDRESS>
</PERSO

 

 

 I am looking to create a SAS data set where the Name is stored in one column, the Home Address and Phone number are stored together in a single column and the Work Address and Phone are stored together in a single column. I have an output XML mapping document that I used to create the XML data set in the first place. Is there any way to modify that to read the data back into SQL as combined columns?

I've never needed to import XML, so I have no experience to base the following comment on.  But if it is easier to import the addresses and phone numbers as separate columns (separate variables in a SAS data set), I'd strongly recommend doing so.  Then you can read that sas dataset in a data step program where you could easily implement combining of addresses with corresponding phone numbers.

 

So first see if you can read the XML as it is currently structured.  I.e. examine the resulting SAS data set to determine what variables have been created.  If that works, you can redefine your question to ask how to combine variables in a data step.  If it doesn't then simplify your question to one focused on making XML import working.

--------------------------
The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data set

Would enabling PROC SORT to simultaneously output multiple datasets be useful? Then vote for
Allow PROC SORT to output multiple datasets

It looks like this documentation page will help you:

Try this code to see if it gives you what you need:
