Structure concept illustration of xml dom-Where is element, where is attribute, and where is text

I haven't touched on XML for a while. Recently I searched for XML data and found myself dizzy in Various XML concepts. It seems that I forgot the structure definition term of XML DOM. A good memory is better than a bad pen, but it is better to extract it.

Instance XML document content:

<? XML version = "1.0" encoding = "UTF-8" ?>

< Catalog Xmlns = "" >

< Book ID = "Bk101" >

< Author > Matthew </ Author >

< Title > XML developer </ Title >

< Genre > Computer </ Genre >

< Price > 44.95 </ Price >

< Publish_date > 2000-10-01 </ Publish_date >

< Description > After an inadvertant </ Description >

</ Book >

< Book ID = "Bk109" >

< Author > Kress, Peter </ Author >

< Title > Paradox lost </ Title >

< Genre > Science Fiction </ Genre >

< Price > 6.95 </ Price >

< Publish_date > 2000-11-02 </ Publish_date >

< Description > James salway discovers </ Description >

</ Book >

</ Catalog >
