7.5.2 The dir Attribute A keyword attribute used to specify the directionality in which human-readable text is to be represented by a user agent (e.g., the text content of the name element, the description element, and the license element). As some operating systems have restrictions on how long a path length can be, authors need to keep the lengths of relative paths at less than 250 bytes

All internal parameter entities are well-formed by definition.A consequence of well-formedness in general entities is that the logical and physical structures in an XML document are properly nested; no start-tag, end-tag, empty-element tag, element, comment, processing instruction, character reference, or entity reference can begin in one entity and end in another. By construction, XML documents are conforming SGML documents.XML documents are made up of storage units called entities, which contain either parsed or unparsed data

Get namespaces from an XML Document with XPathDocument and LINQ to XML - Scott Hanselman

A System.Xml + LINQ to XML Bridge Methods Way How could we do this with the LINQ to XML namespace? Well, pretty much the same way with a much nicer first line (yes, this could be made smaller). Big thanks to Ion Vasilian for setting me straight with this LINQ to XML Query! First we load the XML into an XDocument and ask for the attributes hanging off the root, but we just want namespace declarations

In real life, the XML schemas and database structures will be more complex, but we have enough structure to give you a good idea of what you need to do. In the past, we might use an XPath query or loop through order elements, but in Linq, we can obtain a collection of orders simply by assigning all of the order elements to another object

If you run this method, a new XML file Customers.Xml will be created in your output directory: The Save method on the XDocument lets you easily save the file. Suppose we change our code the create the XML so that the XML belongs to a namespace: We create a XNamespace and set the url of the namespace we want to use

Many thanks! Ben Fox 29 Apr 2009 12:52 PM Thanks so much for the complete example, works perfectly for me! @Glynn: How long did you wait to see if anything came up? It takes my machine 30s - 1min to actually start writing the XML to the console. Eric White - Independant Consultant 22 Feb 2010 5:46 AM Hi David, The approach that I would take is to parameterize the large LINQ to XML functional construction statement

I suppose that makes a certain amount of sense, but it sure wasn't clear (and the older Word 2007 definitely would LET me do it, even though it appears that it shouldn't have. You then run this example code on the document, which creates the custom XML part, creates the custom XML properties part, and then adds the markup to the body of the document that binds each content control to the custom XML

Another useful pair of methods are AddBeforeSelf and AddAfterSelf which, as their names suggest, allow the adding of elements above and below the current element in the tree. You could just assign a new value to the Value property but it is usually easier to use the SetValue method because this performs automatic type conversions

I definitely have this on the list of things to-do, although it might be a few more months before I blog it (there are some additional features of Silverlight like databinding and layout support that will be coming online then). Braulio - Wednesday, August 8, 2007 3:01:26 PM Hi Scott, Is there any quick way to select a single instance of your RSS entry via LINQ and then move that into your FeedDefinition class

In the example above, the employees element is constructed from four XElements, one for each employee, which in turn is constructed from XAttributes and other XElements. The new way Using the classes from the System.Xml.Linq namespace and the features available in .NET 3.5, constructing an XML document is very easy and very readable

There are two events specifically: ChangedChanging As the names suggest, they are fired when changes are made to the document OR specific parts of the document (which, due to deferred execution, may NOT be at the time of query definition). This is just because we have to access that value twice in our query, so rather than accessing it and parsing it twice, we just do it once at the start
