filterChildren

public static Xml.Tag filterChildren(Xml.Tag parent,
                                     java.util.function.Predicate<Content> childTest)

Filter the children of a tag to only those that match the supplied predicate.

Parameters:

parent - the tag whose direct child elements are to be filtered by 'childTest'

childTest - the predicate used to evaluate the direct child elements of 'parent'.

Returns:

'parent' with its children that matched 'childTest'

filterChildren

public static Xml.Tag filterChildren(Xml.Tag parentScope,
                                     Xml.Tag parent,

Filter the children of a tag to only those that match the supplied predicate.

Parameters:

parentScope - a tag which contains 'parent' as a direct or transitive child element.

parent - the tag whose direct child elements are to be filtered by 'childTest'

childTest - the predicate used to evaluate the direct child elements of 'parent'.

Returns:

'parentScope` which somewhere contains 'parent' with its children that matched 'childTest'

filterTagChildren

Returns:

'parent' with its children that matched 'childTest'
