The number of child elements.


First child element or null.


Last child element or null.


The next sibling element or null.


The previous sibling element or null.


Not implemented yet, always return null


The element name


版本 说明
8.0.0 The firstElementChild, lastElementChild, childElementCount, previousElementSibling, and nextElementSibling properties have been added.
8.0.0 DOMElement implements DOMParentNode and DOMChildNode now.



此 DOM 扩展采用 UTF-8 编码。在 ISO-8859-1 编码下,使用 utf8_encode()utf8_decode() 来处理,其它编码下使用 iconv 函数处理。
