an exception is thrown.

Returns the comment children
Returns the child elements obeying the given predicate.
Returns the descendant elements obeying the given predicate.
Returns the descendant-or-self elements obeying the given predicate.
Returns the descendant-or-self elements obeying the given predicate. This method could be defined as:
def filterElemsOrSelf(p: ThisElem => Boolean): immutable.IndexedSeq[ThisElem] = Vector(this).filter(p) ++ (this.findAllChildElems flatMap (_.filterElemsOrSelf(p)))
It can be proven that the result is equivalent to findAllElemsOrSelf filter p.
Returns the element children
Returns all child elements paired with their path entries.
Returns all child elements paired with their path entries.
This method is final, so more efficient implementations for sub-types are not supported. This implementation is only efficient if finding all child elements as well as computing their resolved names is efficient. That is not the case for DOM wrappers or Scala XML Elem wrappers (due to their expensive Scope computations). On the other hand, those wrapper element implementations are convenient, but not intended for heavy use in production. Hence, this method should typically be fast enough.
Returns all descendant elements (not including this element).
Returns this element followed by all descendant elements (that is, the descendant-or-self elements).
Returns the first found ancestor element obeying the given predicate, if any, wrapped in an Option
Returns the first found ancestor element obeying the given predicate, if any, wrapped in an Option
Returns the first found ancestor-or-self element obeying the given predicate, if any, wrapped in an Option

Returns the first found attribute value of an attribute with the given local name, if any, wrapped in an Option.
Returns the first found attribute value of an attribute with the given local name, if any, wrapped in an Option.
Because of differing namespaces, it is possible that more than one such attribute exists, although this is not often the case.
Returns the first found child element obeying the given predicate, if any, wrapped in an Option.
Finds the child element with the given Path.Entry (where this element is the root), if any, wrapped in an Option.
Finds the child element with the given Path.Entry (where this element is the root), if any, wrapped in an Option.
This method is final, so more efficient implementations for sub-types are not supported. This implementation is only efficient if finding all child elements as well as computing their resolved names is efficient. That is not the case for DOM wrappers or Scala XML Elem wrappers (due to their expensive Scope computations). On the other hand, those wrapper element implementations are convenient, but not intended for heavy use in production. Hence, this method should typically be fast enough.
Returns the first found (topmost) descendant element obeying the given predicate, if any, wrapped in an Option.
Returns the first found (topmost) descendant-or-self element obeying the given predicate, if any, wrapped in an Option.
Finds the element with the given Path (where this element is the root), if any, wrapped in an Option.
Finds the element with the given Path (where this element is the root), if any, wrapped in an Option.
That is, returns:
findReverseAncestryOrSelfByPath(path).map(_.last)
Note that for each non-empty Path, we have:
findElemOrSelfByPath(path) == findChildElemByPathEntry(path.firstEntry) flatMap (e => e.findElemOrSelfByPath(path.withoutFirstEntry))Finds the reversed ancestry-or-self of the element with the given Path (where this element is the root),
wrapped in an Option.
Finds the reversed ancestry-or-self of the element with the given Path (where this element is the root),
wrapped in an Option. None is returned if no element can be found at the given Path.
Hence, the resulting element collection, if any, starts with this element and ends with the element at the given Path, relative to this element.
This method comes in handy for (efficiently) computing base URIs, where the (reverse) ancestry-or-self is needed as input.
Returns the descendant elements obeying the given predicate that have no ancestor obeying the predicate.
Returns the descendant-or-self elements obeying the given predicate, such that no ancestor obeys the predicate.
Returns the descendant-or-self elements obeying the given predicate, such that no ancestor obeys the predicate. This method could be defined as:

Returns the single child element obeying the given predicate, and throws an exception otherwise.

Returns the equivalent of scope.resolveQNameOption(textAsQName).get
Returns the text children
Returns text.trim.
Returns text.trim.
Wrapper around
org.w3c.dom.Element, conforming to the eu.cdevreeze.yaidom.queryapi.ElemLike API.See the documentation of the mixed-in query API trait(s) for more details on the uniform query API offered by this class.
By design the only state of the DomElem is the wrapped element. Otherwise it would be easy to cause any inconsistency between this wrapper element and the wrapped element. The down-side is that computing the resolved name or resolved attributes is expensive, because on each call first the in-scope namespaces are computed (by following namespace declarations in the ancestry and in the element itself). This is done for reliable namespace support, independent of namespace-awareness of the underlying element's document.
This choice for reliable namespace support (see the documented properties of
ScopedElemApi) and defensive handling of mutable state makes this DomElem slower (when querying for resolved names or attributes) than other wrapper element implementations, such asScalaXmlElem. On the other hand, if the use oforg.w3c.domis a given, then this DomElem makes namespace-aware querying of DOM elements far easier than direct querying of DOM elements.
