I am using the org.apache.xpath Java package to take in XPath
expressions in text form from a file, transform them with a
XPathVisitor, and emitting them again as text. (This replaces an older
solution that used regexes and was not flexible enough.)
I have had no difficulty with parsing the input into an XPath object and
transforming it, but I cannot figure out how to print out the
transformed XPath (or the Expression inside it).
* Using XPath().getPatternString() returned the original string I
read in, not a string that represented the transformed xpath.
* toString() returns the usual Java "ClassName @ location" string.
* Writing my own Expression-to-String functions looks daunting, due
to the large number of classes that it would have to understand.
Is there an existing stringifying method or a stringifying XPathVisitor
available anywhere? Or is this a totally unsuitable library for my
task? If so, can anyone suggest a suitable replacement?
