Replace module straxpath with new module xpath-absolute
This new module improves performance (same memory consumption, CPU usage reduced):
- create DOM objects only for potentially selected nodes and their ancestors.
- evaluate XPath predicates only for nodes that match depth, namespace and name of potentially selected nodes.
- attribute, text and comment nodes are tested only if their parent element matches the parent of potentially selected nodes.
It also improves reliability: XPath expressions that can not be reliably evaluated in streaming mode are evaluated on a full DOM tree instead.
It supports XML comments.
It has no dependency on any Lavoisier module.
