If you use the Saxon 9.8 Xslt30Transformer you can both set 
http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#applyTemplates-net.sf.saxon.s9api.XdmValue- 
and 
http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#setGlobalContextItem-net.sf.saxon.s9api.XdmItem-

as needed to a sequence of strings for example. I am not sure the 
command line interface of net.sf.saxon.Transform however allows that, so 
to interact with your GNU/Linux pipe you might need to write some Java 
command line program first processing the input and creating/generating 
an XdmValue as needed to then call Xslt30Transformer with that input.

In the XSLT code you can use
  <xsl:template match=".[. instance of xs:string]">
for instance to process a string value.
