retrieving XML information through DOM children elements

Suppose I have an XML object in the following format:

<book id="01">
  <author>Conner, Jim</author>
  <title>House Hunter</title>
  <genre>DIY</genre>
  <price>5.95</price>
  <publish_date>2000-12-16</publish_date>
  <description>A former architect describes his theories 
    on finding best value homes.</description>
</book>

To retrieve the author property, I can use this code:

request.responseXML.getElementsByTagName('book')[0].firstChild.nextSibling

For the title property, I can use:

request.responseXML.getElementsByTagName('book')[0].firstChild.nextSibling.nextSibling.nextSibling

Is there a more efficient way to access this data using vanilla JavaScript, rather than JQuery?

Answer №1

Retrieve Author Information
responseXML.getElementsByTagName('book')[0].getElementsByTagName('author')[0]

Author - plain text
responseXML.getElementsByTagName('book')[0].getElementsByTagName('author')[0].firstChild.data

Get Title
responseXML.getElementsByTagName('book')[0].getElementsByTagName('title')[0]

Title - plain text only 
responseXML.getElementsByTagName('book')[0].getElementsByTagName('title')[0].firstChild.data
