# 🗂️ feed-sifter

**feed-sifter** is a lightweight, cross-platform `PowerShell` script that converts structured `XML` product feeds into flat `CSV` files.  

It’s ideal for B2B/B2C product data processing, price list extraction, or automated data transformation tasks.

---

## 🚀 Features

- ✅ Reads XML feeds from a remote **URL**

- ✅ Extracts **nested fields** (like `selling_prices`) and **root fields**

- ✅ Centralized configuration for feed structure

- ✅ Outputs clean `UTF-8` encoded `CSV`

- ✅ Runs on **Windows**, **macOS**, and **Linux** (via `PowerShell Core`)

---

## 📦 Requirements

On Windows, `PowerShell` should be installed by default. 

- Windows 

  - On Windows: Download from https://github.com/PowerShell/PowerShell

- PowerShell Core (`pwsh`)

  - On macOS/Linux: `brew install --cask powershell`

---

## 🔧 Usage

### 🪟 Windows 

```powershell

# For a CSV output

.\SiftFeedWHeader.ps1 -xmlUrl "https://example.com/path/to/feed.xml"

# For a XML output

.\SiftFeedXml.ps1 -xmlUrl "https://example.com/path/to/feed.xml"

```

###  MacOS

```bash

# For a CSV output

pwsh ./SiftFeedWHeader.ps1 -xmlUrl "https://example.com/path/to/feed.xml"

# For a XML output 

pwsh ./SiftFeedXml.ps1 -xmlUrl "https://example.com/path/to/feed.xml"

```

### Parameters

| Parameter | Description |

|----------|-------------|

| `-xmlUrl` | **(Required)** URL of the remote XML feed you want to process |

---

## 🧠 Feed Structure Configuration

Inside the script, you can easily configure the feed structure:

```powershell

$feedStructure = @{

    # XML path to repeating items

    rootPath = "//item"     

    nestedRepeats = @{

         # nested arrays

        selling_prices = @("currency", "base_price", "discount_price")         

    }

    # root-level fields

    flatFields = @("ean", "availability", "availability_count")         

}

```

Just modify the `flatFields` or `nestedRepeats` arrays to match your `XML` feed layout.

---

## 📁 Output

The resulting `output.csv` file will be written to the script's current working directory.  

It contains headers and all mapped values from the `XML` feed.

Example output:

```csv

ean,availability,availability_count,currency,base_price,discount_price

20000000025,in stock,14,CZK,2500,1999

...

```

---

## 💡 Tips

- Works with `HTTPS` feeds and requires no authentication.

- To change output file name or encoding, modify the `$outputPath` and `Set-Content`/`Add-Content` lines.

- You can redirect output to a timestamped file for batch jobs.

---

## 🔐 Execution Policy Troubleshooting

If you're running the script and see an error like:

```text

File cannot be loaded because running scripts is disabled on this system.

```

This means PowerShell's **execution policy** is blocking script execution.

### ✅ Temporary Fix (Safe for Local Use)

Run this in your current terminal session **before executing the script**:

```powershell

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

```
