StXPathSetPosition

Syntax

StXPathSetPosition(pos);

pos	An integer specifying the traversing position in the node set, where 1 represents the first position in the node set.

Description

Sets the traversing position inside the node set that has been pushed onto the memory stack.

Returns

	The position points to a valid node.
	The position points outside the range of valid nodes. Note: The position is still set within the data context. For example, this enables you to reset the position to 0 before re-entering a loop that uses the StXPathNextPosition function.

Example

num i, count = StXPathPushNodeSet("/data/message/item[number(value)>100]");

for ( i=count; stXPathSetPosition(i); i-- )

{

		    $descs[arraySize($descs)] = stEvalXpath("item_description");

}

StXPathPopNodeSet();
