Bodu.Xml.Linq Namespace

Package

Bodu.Core 1.0.1

Purpose

Bodu.Xml.Linq is a small XML / LINQ-to-XML helper namespace used internally by Bodu.Globalization.Calendar's rule parsers and exposed for consumers who need the same primitives. Reach for it when you need to resolve namespace prefixes against a fragment of LINQ-to-XML without standing up a full XmlNameTable.

Key types

• XmlNamespaceResolver - implements IXmlNamespaceResolver over an XElement so XPath / prefix-aware queries can be evaluated against a LINQ-to-XML fragment.

Example

using System.Xml.Linq;
using System.Xml.XPath;
using Bodu.Xml.Linq;

XElement root = XElement.Parse(xml);
var resolver = new XmlNamespaceResolver(root);

IEnumerable<XElement> matches = root.XPathSelectElements(
    "//bc:NotableDate[@territory='AU']",
    resolver);

Notes

• Single-fragment scope. The resolver reflects the element's in-scope namespaces only; declarations on ancestors outside the fragment are not visible.
• Calendar rule documents. Authored notable-date rule files use the urn:bodu:globalization:calendar namespace; this helper resolves in-scope namespace prefixes when reading prefixed elements from such a fragment.
• See also: the Bodu.Core introduction and Bodu.Globalization.Calendar.

Classes

XmlNamespaceResolver

Resolves child XElement and XName instances against the default XML namespace of a supplied root element, removing the need to qualify every lookup with an inline namespace prefix.
