XPath expression

Category: Code

Status: Registered and callable in the CyberChef 11.3.0 compatibility inventory.

Input / output: string → string

Background: https://wikipedia.org/wiki/XPath

What it does

Extract information from an XML document with an XPath query

Note

Status here means the operation name is implemented and callable. It does not by itself promise byte-for-byte parity for every upstream option. See Compatibility and current status for the verified scope and known boundaries.

Arguments and options

Arguments are positional. Keep their order when using bake() or Pipeline.then().

Index	Name	UI type	PyChef default	Accepted values / format
`0`	XPath	`string`	`''`	`''`
`1`	Result delimiter	`binaryShortString`	`'\\n'`	`'\\n'`

Recipe template

Important

This is a call template built from the documented defaults. Replace placeholder values such as empty keys, paths, patterns, or lookup data before running it.

from pychef import bake

input_value = "example"
args = ['', '\\n']
result = bake(input_value, [{"op": 'XPath expression', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = ['', '\\n']
transform = Pipeline().then('XPath expression', *args)
result = transform("example")

Dedicated operation module

The registered entry point lives in pychef.operations.by_operation.xpath_expression. Direct calls receive the input value and a positional argument tuple:

from pychef.operations.by_operation.xpath_expression import run

result = run("example", tuple(['', '\\n']))

pychef.operations.by_operation.xpath_expression.run(value, args)

Run this operation using its shared internal implementation.

Parameters:

value (str | bytes)
args (Sequence[Any])

Return type:

str | bytes
