HTML Streaming Editor

Run (simple) manipulations on HTML files, like extracting parts. Use CSS selectors to define which parts of the HTML to operator on, use different commands in pipes to perform the desired operations.

Syntax

The basic syntax is:

(COMMAND SELECTOR) | (COMMAND SELECTOR)

Some COMMAND use sub-pipelines, those would be written as follows:

(COMMAND SELECTOR {(COMMAND SELECTOR) | (COMMAND SELECTOR)})

The SELECTOR is a CSS selector, wrapped in either ", ' or ? (as to reduce the necessity of escaping to a minimum).

Commands

Planned commands: - ONLY: remove everything not matching the CSS selector - FILTER: remove everything matching the CSS selector - MAP: run the nodes matching the CSS selector through a sub-pipeline and replace them with the result of that pipeline - Some attribute & text-content manipulation

Currently supported: - ONLY - FILTER is in code, but mis-behaves

Binary

The binary is called hse and supports following options:

``` USAGE: hse [OPTIONS]

ARGS: Single string with the command pipeline to perform

OPTIONS: -h, --help Print help information -i, --input File name of the Input. - for stdin (default) -o, --output

File name of the Output. - for stdout (default) -V, --version Print version information ```

Example

```shell

fetches all elements with CSS class "content" inside a

element

hse -i index.html '(ONLY ?header .content?)' ```
