Function XMLDocSetAction() Professional
Set action code blocks for specific tags.
XMLDocSetAction( <nDocHandle>, <cNode>, <bAction> ) --> nTagCount
|cTagName||Name of the tag as character string.|
|xTagContent||Content of XML tag as character string or NIL.|
|xTagAttr||Two-column array holding name/value pairs for tag attributes, or NIL if the tag has no attributes.|
|nTagHandle||Numeric tag handle.|
|XML_PROCESS_ABORT||Aborts execution of other action code blocks|
|XML_PROCESS_CONTINUE||Executes next action codeblock|
The function returns the number of tags, or nodes, matching the string <cNode>.
This function registers a code block in the parser engine and defines the nodes in the XML document for which the code block <bAction>must be evaluated. The code block usually calls a user-defined function which implements the action for the parser engine when it finds a matching node.
To explain the required syntax for <cNode>, the following XML code is used:
To pass the contents of the various XML tags to the action code block, the following node strings could be used for <cNode>.
The first node string in this example defines a complete path to the data embedded in the <order> tags. The following examples demonstrate the meaning of the double slash. "//" is interpreted like a wildcard that matches any possible path. This means that "//" alone matches all nodes, while "/Configuration//load" matches all <load> tags appearing within the root tag of the example. In this case, "//" matches the tags <DatabaseEngines> and <DynamicDLLs>.
