# XMLUtils

### Purpose
This module provides utility classes for handling XML data specific to the DTS system. It includes helpers for reading XML files with specific DTS metadata structures, a generic wrapper for serializing nullable types without standard `xsi:nil` attributes, and a parser for aggregating test metadata from multiple files.

### Public Interface

**`static class DTSXMLFile`**
*   `double GetItemsToCompleteCount(string fileName)`: Reads an XML file specified by `fileName` and extracts the `TotalItems` attribute from the root node. Returns `0.0` if the attribute is missing or an error occurs.
*   `string GetInnerXML(XmlReader reader)`: Reads the inner text of an XML element using the provided `XmlReader`. Throws `ArgumentException` if the reader is null.

**`class NullableElement<T>`**
*   `NullableElement()`: Initializes a new instance with no value (`HasValue` is false).
*   `NullableElement(T value)`: Initializes a new instance with the specified value.
*   `
