xml-find searches the contents of FILE like a directory tree, and evaluates the given EXPRESSION on each encountered tag. The search starts at each XPATH associated with FILE, according to the common unified command line convention described in xml-coreutils(7). For each tag, the EXPRESSION is evaluated from left to right and any actions are performed as required, after which xml-find moves to the next tag. If no EXPRESSION is specified, the EXPRESSION is assumed to be -print.

EXPRESSION

An expression is a sequence of actions to be performed in order for each current node, while the XML document is being traversed. Each action can be followed by zero or more arguments, and also evaluates to true or false. When some action evaluates to false, the subsequent actions are not evaluated. The available actions are:

	-print		Prints the XPATH for the current node.
	-exec		Execute PROGRAM with the optional list of ARG arguments. The final semicolon indicates the end of arguments, and must be supplied even if no arguments are given. There are three special arguments, {} expands to the path for the currently visited tag, {@} expands to a list of attributes and values associated with the current tag, and {-} expands to the name of a temporary file which contains a copy of the currently visited node. Evaluates to true if PROGRAM returns zero, and false otherwise.

-execnode

Similar to -exec, but all paths are relative to the current node.

	-name		Checks to see if the currently visited tag name matches the shell glob PATTERN. Returns true on a match, false otherwise.
	-path		Checks to see if the path for the currently visited tag matches the shell glob PATTERN. Returns true on a match, false otherwise.
	’(’		Represents a block of actions. Returns true if every optional ACTION returns true, and false otherwise.
	’!’		Negates the value of ACTION. Returns true if ACTION returns false, and vice versa.

ACTION1

Evaluates ACTION2 if and only if ACTION1 returns true. Returns true if both ACTION1 and ACTION2 evaluate to true, false otherwise.

ACTION1

Evaluates ACTION2 if and only if ACTION1 returns false. Returns the value of ACTION1 if true, or the value of ACTION2 otherwise.

EXIT STATUS

xml-find returns 0 on success, or 1 otherwise.

EXAMPLE

Identify all the tag addresses which match a given XPATH:

xml-find movies.rss :/rss/channel -print

For each matching node, print all of its attributes:

xml-find movies.rss ://media:content -exec echo {@} ;
