This is simplified xpath function generator for .NET.

## Requirement

- Each parser (e.g. HtmlAgilityPack)

## Usage

In this case, use HtmlAgilityPack together.

1. Install XPath.

2. Create class `XPathRetriveConfig.`

	```csharp

	internal sealed class HtmlAgilityXPathRetriveConfig : IXPathRetriveConfig

	{

		public static HtmlAgilityXPathRetriveConfig Instance { get { return _Instance ?? (_Instance = new HtmlAgilityXPathRetriveConfig()); } }

		private static HtmlAgilityXPathRetriveConfig _Instance = null;

		private HtmlAgilityXPathRetriveConfig() { }

		public Expression>> ChildrenGetter => node => node.ChildNodes;

		public Expression> TagNameGetter => node => node.Name;

		public Expression> TextGetter => node => node.InnerText;

		public Expression> AttributeValueGetter => (node, name) => node.GetAttributeValue(name, string.Empty);

	}

	```

3. Compile function and parse.

	```csharp

	public string GetFirstDivText(string html)

	{

		var func = XPathExpression.Compile("/html/body/div[0]/text()", HtmlAgilityXPathRetriveConfig.Instance);

		var doc = new HtmlDocument();

		doc.Load(new StringReader(html));

		var result = func(new[] { doc.DocumentNode }).Single();

		return result;

	}

	```
