# 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.
* `
