### Install strip-tags Dependencies

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This command installs the project's dependencies, including testing dependencies, in editable mode. The `-e` flag allows the project to be installed directly from the source directory, which is useful during development. The `.[test]` syntax specifies that both the main package and its test extras should be installed.

```bash
pip install -e '.[test]'
```

--------------------------------

### Install strip-tags using pip

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This command installs the strip-tags package using pip, making it available for use in your Python environment. Ensure you have pip installed and configured.

```bash
pip install strip-tags
```

--------------------------------

### Strip all tags from HTML via stdin

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This example demonstrates piping HTML content from a file (`input.html`) into the `strip-tags` command-line tool, which then outputs the content with all HTML tags removed to `output.txt`. This is a common use case for cleaning HTML.

```bash
cat input.html | strip-tags > output.txt
```

--------------------------------

### Keep tag bundles

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This example shows how to use predefined bundles of tags with the `-t` option in `strip-tags`. For instance, `-t hs` keeps all heading tags (`<h1>` through `<h6>`).

```bash
strip-tags -t hs
```

--------------------------------

### Remove blank lines with strip-tags

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This Python example shows how to use the `remove_blank_lines=True` argument with the `strip_tags` function to eliminate any remaining empty lines in the processed HTML output.

```python
from strip_tags import strip_tags

html = """
<div>
<h1>This has tags</h1>

<p>And whitespace too</p>
</div>
Ignore this bit.
"""
stripped = strip_tags(html, remove_blank_lines=True)
print(stripped)
```

--------------------------------

### Get only the first matching element's content

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This command uses the `--first` flag with `strip-tags` to extract and return the content of only the first HTML element that matches the provided CSS selector (`.content`). The output is redirected to `output.txt`.

```bash
cat input.html | strip-tags .content --first > output.txt
```

--------------------------------

### Strip tags from specific CSS selectors

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This usage example demonstrates stripping HTML tags only from elements that match the specified CSS selector (e.g., `.content`). It reads from `input.html` and writes the result to `output.txt`.

```bash
strip-tags '.content' -i input.html > output.txt
```

--------------------------------

### Remove content within specified tags

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This example uses the `-r` or `--remove` flag with `strip-tags` to remove entire sections of HTML identified by a tag name (e.g., `nav`). The content is piped in and the result is saved to `output.txt`.

```bash
cat input.html | strip-tags -r nav > output.txt
```

--------------------------------

### Set Up Python Virtual Environment for strip-tags

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This code demonstrates the steps to set up a Python virtual environment for the strip-tags project. It includes navigating to the project directory, creating a virtual environment, and activating it. This is a standard practice for managing project dependencies.

```bash
cd strip-tags
python -m venv venv
source venv/bin/activate
```

--------------------------------

### Run strip-tags module using python -m

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This shows an alternative way to execute the `strip-tags` functionality by calling it as a Python module using `python -m strip_tags`. The `--help` flag is used to display available options.

```bash
python -m strip_tags --help
```

--------------------------------

### Run Tests for strip-tags

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This command executes the test suite for the strip-tags project using the pytest framework. Running tests is crucial for verifying the correctness of the code and ensuring that new changes do not introduce regressions. Pytest is a popular choice for Python testing due to its simplicity and powerful features.

```bash
pytest
```

--------------------------------

### Display strip-tags CLI Help Information

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This snippet shows the help message for the strip-tags command-line tool. It demonstrates the available options for stripping HTML tags and filtering content using CSS selectors. It's useful for understanding the tool's capabilities and usage patterns.

```text
Usage: strip-tags [OPTIONS] [SELECTORS]...

  Strip tags from HTML, optionally from areas identified by CSS selectors

  Example usage:

      cat input.html | strip-tags > output.txt

  To run against just specific areas identified by CSS selectors:

      cat input.html | strip-tags .entry .footer > output.txt

Options:
  --version             Show the version and exit.
  -r, --remove TEXT     Remove content in these selectors
  -i, --input FILENAME  Input file
  -m, --minify          Minify whitespace
  -t, --keep-tag TEXT   Keep these <tags>
  --all-attrs           Include all attributes on kept tags
  --first               First element matching the selectors
  --help                Show this message and exit.

```

### Strip tags from HTML using a filename input

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This shows how to use the `strip-tags` command-line tool by providing the input HTML file directly using the `-i` flag. The output, with tags stripped, is redirected to `output.txt`.

```bash
strip-tags -i input.html > output.txt
```

--------------------------------

### Use strip-tags as a Python library

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This Python code snippet demonstrates how to import and use the `strip_tags` function from the `strip_tags` library. It shows stripping tags from an HTML string, applying CSS selectors, minifying whitespace, and keeping specific tags.

```python
from strip_tags import strip_tags

html = """
<div>
<h1>This has tags</h1>

<p>And whitespace too</p>
</div>
Ignore this bit.
"""
stripped = strip_tags(html, ["div"], minify=True, keep_tags=["h1"])
print(stripped)
```

--------------------------------

### Minify whitespace in HTML content

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This demonstrates the `--minify` or `-m` flag for `strip-tags`, which reduces multiple spaces and tabs to single spaces and removes blank lines, cleaning up whitespace. Input is piped and output is saved to `output.txt`.

```bash
cat input.html | strip-tags -m > output.txt
```

--------------------------------

### Strip tags from multiple CSS selectors

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This shows how to provide multiple CSS selectors to `strip-tags` to strip tags from different sections of an HTML document, read from `input.html` and output to `output.txt`.

```bash
cat input.html | strip-tags '.content' '.sidebar' > output.txt
```

--------------------------------

### strip-tags Python function signature

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This displays the function signature for `strip_tags` when used as a Python library. It outlines the available parameters for input, selectors, removal, minification, and tag keeping.

```python
def strip_tags(
    input: str,
    selectors: Optional[Iterable[str]]=None,
    *,
    removes: Optional[Iterable[str]]=None,
    minify: bool=False,
    remove_blank_lines: bool=False,
    first: bool=False,
    keep_tags: Optional[Iterable[str]]=None,
    all_attrs: bool=False
) -> str:
```

--------------------------------

### Keep specific tags using -t flag

Source: https://github.com/simonw/strip-tags/blob/main/README.md

This command demonstrates how to use the `-t` or `--keep-tag` option with `strip-tags` to preserve specific HTML tags (e.g., `<h1>`, `<li>`) while stripping others. It fetches content from a URL and processes it.

```bash
curl -s https://datasette.io/ | strip-tags header -t h1 -t li
```
