ApplyImportsAction
,NextMatchAction
This watch implements xsl:apply-templates in streaming mode. It watches for the nodes selected by the
xsl:apply-templates instruction; when such a node is encountered, it locates the relevant (inverted)
template, and activates it.

startSelectedParentNode
public Receiver startSelectedParentNode(FleetingParentNode node, Location locationId) throws XPathException Signal that an element or document node has been found that matches the selection that this Watch is looking for. This method is called by the WatchManager while processing the startElement or startDocument event that matches the selection.- Overrides:
startSelectedParentNode
in classItemFeed
- Parameters:
node
- the element or document node whose start event has been matchedlocationId
- the location associated with the element or document node (may be the location of the instruction that created it)- Returns:
- a Receiver to be notified of all events starting with the startElement/startDocument event for the matched element, and ending with the endElement event for that element; or null if this feature is not required.
- Throws:
XPathException
- May be raised if a dynamic error occurs
-
getRule
Get the template rule matching a specific node- Parameters:
node
- the node (in a streamed input document) to be matched- Returns:
- the best-fit template rule used to process this node
- Throws:
XPathException
- if a dynamic error occurs
-
append
Signal that a item (other than a streamed element) that matches the selection has been found.- Specified by:
append
in interfaceReceiver
- Specified by:
append
in classItemFeed
- Parameters:
item
- the item that was matched.- Throws:
XPathException
- if the operation fails
-
endSelectedParentNode
Signal that the endElement event has occurred for the element whose startElement event caused the Watch to be activated.- Overrides:
endSelectedParentNode
in classItemFeed
- Parameters:
locationId
- the location of the node in the source, or of the instruction that created it- Throws:
ValidationException
- May be raised if the constraint implemented by this Watch is violated @param locationId the location of the node in the source, or of the instruction that created itXPathException
- May be raised if a constraint implemented by this Watch is violated
-
close
Description copied from class:ItemFeed
Finish evaluating the expression.- Specified by:
close
in interfaceReceiver
- Overrides:
close
in classItemFeed
- Throws:
XPathException
- if a dynamic error occurs
