Replaces this object with another object. Basically, calls Parent.replace_child

Returns

self

Sets the previous sibling of this child. This can be used to insert a child before some other child.

a = Element.new("a")
b = a.add_element("b")
c = Element.new("c")
b.previous_sibling = c
# => <a><b/><c/></a>

Adds a child to this element, optionally setting attributes in the element.

element

optional. If Element, the element is added. Otherwise, a new Element is constructed with the argument (see Element.initialize).

attrs

If supplied, must be a Hash containing String name,value pairs, which will be used to set the attributes of the new Element.

Returns

the Element that was added

el = doc.add_element 'my-tag'
el = doc.add_element 'my-tag', {'attr1'=>'val1', 'attr2'=>'val2'}
el = Element.new 'my-tag'
doc.add_element el

Deletes a child element.

element

Must be an Element, String, or Integer. If Element, the element is removed. If String, the element is found (via XPath) and removed. <em>This means that any parent can remove any descendant.<em> If Integer, the Element indexed by that number will be removed.

Returns

the element that was removed.

doc.delete_element "/a/b/c[@id='4']"
doc.delete_element doc.elements["//k"]
doc.delete_element 1

Evaluates to true if this element has at least one child Element

doc = Document.new "<a><b/><c>Text</c></a>"
doc.root.has_elements               # -> true
doc.elements["/a/b"].has_elements   # -> false
doc.elements["/a/c"].has_elements   # -> false

Synonym for Element.elements.each

Synonym for Element.to_a This is a little slower than calling elements.each directly.

xpath

any XPath by which to search for elements in the tree

Returns

an array of Elements that match the supplied path

Returns the next sibling that is an element, or nil if there is no Element sibling after this one

doc = Document.new '<a><b/>text<c/></a>'
doc.root.elements['b'].next_element          #-> <c/>
doc.root.elements['c'].next_element          #-> nil

Replaces one child with another, making sure the nodelist is correct @param to_replace the child to replace (must be a Child) @param replacement the child to insert into the nodelist (must be a Child)

Generates a Source object @param arg Either a String, or an IO @return a Source, or nil if a bad argument was given

@return the current line in the source

@return the current line in the source

Reads all tuples matching tuple from the proxied TupleSpace. See TupleSpace#read_all.

Creates a thread that notifies waiting clients from the TupleSpace.

Pulls lookup tuples out of the TupleSpace and sends their DRb object the address of the local TupleSpace.

Returns an expiry Time based on sec which can be one of:

Numeric

sec seconds into the future

true

the expiry time is the start of 1970 (i.e. expired)

nil

it is Tue Jan 19 03:14:07 GMT Standard Time 2038 (i.e. when UNIX clocks will die)

Returns a valid argument to make_expires and the renewer or nil.

Given true, nil, or Numeric, returns that value and nil (no actual renewer). Otherwise it returns an expiry value from calling it.renew and the renewer.

true if the TupleBag to see if it has any expired entries.

Returns all tuples matching tuple. Does not remove the found tuples.

Notifies all registered listeners for event of a status change of tuple.
