fhir_xpath_expression

This function takes a character vector, checks whether it contains valid XPath (1.0) expressions
and returns it as an fhir_xpath_expression object. These objects are used in <code>fhir_parameters</code> objects.

Useful tools for conveniently downloading FHIR resources in xml format
and converting them to R data.frames. The package uses FHIR-search to download bundles
from a FHIR server, provides functions to save and read xml-files containing such bundles
and allows flattening the bundles to data.frames using XPath expressions. FHIR® is the registered trademark
