XPath-aware taxonomy querying support. In TQA no taxonomy XPath awareness is anywhere outside of this namespace. This implies that all of TQA outside of this namespace (and the xpath namespace) can be used without the need for any XPath processor. Everything inside this namespace does need an XPath processor, though.

Dependency on XPath processing for taxonomy querying and processing is not without its costs:

Some XPath expressions may be somewhat brittle and give inconsistent results among XPath processors
All prefixes used in XPath expressions must be bound to namespaces
The backing element implementation used is coupled to the XPath processor used. In practice, use Saxon for XPath processing and backing elements
Configuration of the XPath processor may be sensitive, not only w.r.t. namespaces, but also w.r.t. the base URI, etc.
It may be challenging to find the optimal lifetime of XPath evaluators and compiled XPath expressions, balancing between performance and clarity.

Type Members

trait ValueOrExprEvaluator[A] extends AnyRef

XPath-aware evaluator of a ValueOrExpr for some type A.

Value Members

object BigDecimalValueOrExprEvaluator extends ValueOrExprEvaluator[BigDecimal]

XPath-aware evaluator of a BigDecimalValueOrExpr.
XPath-aware evaluator of a BigDecimalValueOrExpr. XPath evaluation is performed without any context item. Make sure to use an XPathEvaluator that knows about the needed namespace bindings in the XPath expressions.
object ENameValueOrExprEvaluator extends ValueOrExprEvaluator[EName]

XPath-aware evaluator of a ENameValueOrExpr.
XPath-aware evaluator of a ENameValueOrExpr. XPath evaluation is performed without any context item. Make sure to use an XPathEvaluator that knows about the needed namespace bindings in the XPath expressions.
object StringValueOrExprEvaluator extends ValueOrExprEvaluator[String]

XPath-aware evaluator of a StringValueOrExpr.
XPath-aware evaluator of a StringValueOrExpr. XPath evaluation is performed without any context item. Make sure to use an XPathEvaluator that knows about the needed namespace bindings in the XPath expressions.
