Description

Fields

namespaceURLOrPrefix: string;

Namespace the matched node must be in (only used if qmCheckNamespace is set)

value: string;

If value <> '', only nodes with the corresponding value are found (value = node-name for element node, value = text for text/comment nodes)

valueHash: cardinal;
 
filters: TXQPathMatchingStepFilters;

expressions a matched node must satisfy

requiredType: TXQTermSequenceType;
 
typ: TXQPathMatchingAxis

Axis, where it searchs for a matching tree node

matching: TXQPathMatchingKinds;

Which nodes match the query command. If this is [], _nothing_ is found! The elements of the set [qmElement,qmText,qmComment,qmProcessingInstruction,qmAttribute] match nodes of a certain type, qmValue activates the value field.

specialCase: TXQTerm;

Term used for qcFunctionSpecialCase
