The output from running the following command is concatenated together, how do I add a new line to each result?

Here is the xml file:

Here is the command I'm running to select the value between the pdf_name tags

bash$ xmllint --xpath '//airport_name[@apt_ident="ADK"]/record[chart_code="IAP" or "DP" or "STAR" or "APD"]/pdf_name/text()' file.xml

Here is what the output looks like, as you can see it is missing new lines between the values returned, how do I add new lines?

AKTO.PDF01244R23.PDF01244ND23.PDFbash$

I want the output to look like this

AKTO.PDF
01244R23.PDF
01244ND23.PDF

The output of xmllint is correct. The text nodes containing the newlines
are not selected by the given XPath expression.

To add newlines after each matched node you have to use a different
tool. You could write an XSLT transformation (instead of just a XPath
expression) and apply it with an XSLT processor.

Fortunately, there is xmlstarlet (the executable is "xml"), that you can
use instead of xmllint. xmlstarlet is a tool that automagically can
internally create the XSLT for you in some simple cases.

The particular command line in your case is (warning, single long line
probably wrapped in the message):

xml sel -t -m "//airport_name[@apt_ident='ADK']/record[chart_code='IAP'
or 'D P' or 'STAR' or 'APD']/pdf_name/text()" -c "." -n file.xml

It gives:

AKTO.PDF
01244R23.PDF
01244ND23.PDF

Caveat: it takes some time to master the intricacies of the command line
parameters of xmlstarlet.
