xpath
XPATH(1p) User Contributed Perl Documentation XPATH(1p) NAME
xpath - a script to query XPath statements in XML documents. SYNOPSIS
xpath [-s suffix] [-p prefix] [-q] -e query [-e query] ... [file] ... DESCRIPTION
xpath uses the XML::XPath perl module to make XPath queries to any XML document. The XML::XPath module aims to comply exactly to the XPath specification at "http://www.w3.org/TR/xpath" and yet allows extensions to be added in the form of functions. The script takes any number of XPath pointers and tries to apply them to each XML document given on the command line. If no file arguments are given, the query is done using "STDIN" as an XML document. When multiple queries exist, the result of the last query is used as context for the next query and only the result of the last one is output. The context of the first query is always the root of the current document. OPTIONS
-q Be quiet. Output only errors (and no separator) on stderr. -s suffix Place "suffix" at the end of each entry. Default is a linefeed. -p prefix Place "prefix" preceding each entry. Default is nothing. BUGS
