|
| <DD>The exsl:object-type function returns a string giving the type of the object passed |
| as the argument. The possible object types are: 'string', 'number', 'boolean', |
| 'node-set', 'RTF', or 'external'. |
| |
| Most XSLT object types can be coerced to each other without error. However, there are |
| certain coercions that raise errors, most importantly treating anything other than a |
| node set as a node set. Authors of utilities such as named templates or user-defined |
| extension functions may wish to give some flexibility in the parameter and argument values |
| that are accepted by the utility; the exsl:object-type function enables them to do so. |
| |
| The Xalan extensions MethodResolver converts 'object-type' to 'objectType'.<DD><DL>

|
| <DD>The exsl:node-set function converts a result tree fragment (which is what you get |
| when you use the content of xsl:variable rather than its select attribute to give |
| a variable value) into a node set. This enables you to process the XML that you create |
| within a variable, and therefore do multi-step processing. |
| |
| You can also use this function to turn a string into a text node, which is helpful |
| if you want to pass a string to a function that only accepts a node set. |
