Xml file processing




















If the name of the item itself contains periods, they are replaced by the number sign. It is assumed that no item has a number sign directly in its name. For example, the fully qualified name of the String constructor would be System. For properties and methods, if there are arguments to the method, the argument list enclosed in parentheses follows. If there are no arguments, no parentheses are present.

The arguments are separated by commas. The encoding of each argument follows directly how it is encoded in a. NET Framework signature. Skip to main content. The arguments are separated by commas. Each argument is encoded the same way it's encoded in a. NET Framework signature:. Base types. Int32 or System. The MSVC compiler never generates this element. If a lower bound or size isn't specified, it's omitted. If the lower bound and size are omitted for a particular dimension, the ' : ' is omitted as well.

For example, a 2-dimensional array with 1 as the lower bound and unspecified sizes is represented as [1:,1:]. If there are no arguments, the parentheses are omitted.

The following signature components aren't represented because they're never used for differentiating overloaded methods:. For generic types, the name of the type will be followed by a back tick and then a number that indicates the number of generic type parameters. For example,. Each number represents a zero-based array position for the type's generic parameters. The complete source code for this example is available for download with this article at the link at the top of this article.

The problem is that I want to generate a table header that includes the name of each element but remains generic.

Any ideas? If you are, use an xsl:for-each statement to walk through each of its child elements to output its name, as shown here:. You can also accomplish this using xsl:apply-templates instead of xsl:for-each , but it requires the use of XSLT modes.

The XSLT language offers template modes to help deal with situations in which a given set of nodes needs to be processed in multiple passes. For example, your original program could be rewritten as shown in Figure 7. Modes play an important role in XSLT's declarative programming model and are often required when you have to deal with complex transformations.

Here's the sample equation that I'm using:. A The reason this turns out to be quite difficult is that XSLT variables don't behave like variables in most imperative programming languages.

Nevertheless, you'll need to use them to solve this problem along with the help of recursion. Marvin Smit, an attendee at a recent conference at which I appeared, offered an elegant solution that uses a combination of xsl:apply-templates and xsl:value- of instructions to recursively process the equation see Figure 8. I've provided the equation document, this solution, and a procedural solution which uses named templates and xsl:call-template in the sample code associated with this column.

There is an overload that takes an IXPathNavigable reference. How do I get the result of a transform that returns text without writing it to a file? I need it as a string. Instead, you need to supply it with either a Stream or TextWriter object to which it can write the results. Since you want the results as a String, you should supply Transform with a StringWriter object, as shown here:.

Q I'm hearing a lot more about the Infoset these days—what exactly is it again? Figure 9 Infoset. The XML 1. After XML 1. Each of these layered specifications had to infer the logical XML data model from the original specification since it hadn't been codified. Because this was happening it became apparent that the various specifications didn't agree on what the implied data model should be. As an example, consider the simple question of whether an attribute node should have a parent property.
