Returns the child elements obeying the given predicate.
Returns the child elements obeying the given predicate. This method could be defined as:
def filterChildElems(p: E => Boolean): immutable.IndexedSeq[E] = this.findAllChildElems.filter(p)
Returns the descendant elements obeying the given predicate.
Returns the descendant elements obeying the given predicate. This method could be defined as:
this.findAllChildElems flatMap (_.filterElemsOrSelf(p))
Returns the descendant-or-self elements obeying the given predicate.

def filterElemsOrSelf(p: E => Boolean): immutable.IndexedSeq[E] = Vector(this).filter(p) ++ (this.findAllChildElems flatMap (_.filterElemsOrSelf(p)))
It can be proven that the result is equivalent to findAllElemsOrSelf filter p
.
Core method that returns all child elements, in the correct order.
Core method that returns all child elements, in the correct order. Other operations can be defined in terms of this one.
Returns all child elements paired with their path entries.
Returns all descendant elements (not including this element).

.
Equivalent to findAllElemsOrSelf.drop(1)
.

Returns this element followed by all descendant elements (that is, the descendant-or-self elements).
This method could be defined as filterElemsOrSelf { e => true }
.
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
.
Returns the first found child element obeying the given predicate, if any, wrapped in an Option
.
This method could be defined as filterChildElems(p).headOption
.
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
.
Typically this method must be very efficient, in order for methods like findElemOrSelfByPath to be efficient.
Returns the first found (topmost) descendant element obeying the given predicate, if any, wrapped in an Option
.
Returns the first found (topmost) descendant element obeying the given predicate, if any, wrapped in an Option
.
This method could be defined as filterElems(p).headOption
.
Returns the first found (topmost) descendant-or-self 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
.
This method could be defined as filterElemsOrSelf(p).headOption
.
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 elements obeying the given predicate that have no ancestor obeying the predicate. This method could be defined as:
this.findAllChildElems flatMap (_.findTopmostElemsOrSelf(p))
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:
def findTopmostElemsOrSelf(p: E => Boolean): immutable.IndexedSeq[E] = if (p(this)) Vector(this) else (this.findAllChildElems flatMap (_.findTopmostElemsOrSelf(p)))
Returns the single child element obeying the given predicate, and throws an exception otherwise.
Returns the single child element obeying the given predicate, and throws an exception otherwise.
This method could be defined as findChildElem(p).get
.
Returns (the equivalent of) findChildElemByPathEntry(entry).get
Returns (the equivalent of) findChildElemByPathEntry(entry).get
Returns (the equivalent of) findElemOrSelfByPath(path).get

Returns the concatenation of the text values of (the implicit) text children, including whitespace and CData.
Returns the concatenation of the text values of (the implicit) text children, including whitespace and CData. Non-text children are ignored. If there are no text children, the empty string is returned.
Therefore, element children are ignored and do not contribute to the resulting text string.
Returns text.trim
.
Returns text.trim
.
Shorthand for
ElemApi[E] with IsNavigableApi[E] with HasENameApi with HasTextApi
. In other words, the minimal element query API corresponding to James Clark's "labelled element tree" abstraction, which is implemented as yaidom "resolved" elements.If a yaidom element implementation (whether in yaidom itself or a "yaidom extension") does not mix in the
ClarkElemApi
trait, it is probably not to be considered "XML". Indeed, in yaidom only theElemBuilder
class does not mix in this trait, and indeed it is not "XML" (lacking any knowledge about expanded names etc.), only a builder of "XML". Hence this trait is very important in yaidom, as the "minimal XML element query API".Generic code abstracting over yaidom element implementations should either use this trait, or sub-trait
ScopedElemApi
, depending on the abstraction level.The captured element subtype
