RE: [flexcoders] Alternative to firstChild, lastChild and nextSibling

Compare it to the Microsoft XML DOM, which has dozens of classes.  “XML”, huh, one class? How can that be?

You got that right! E4x can do some crazy things. Sometimes I wonder if I am kidding myself at how easy it is to use :)

Peace, Mike

Hi everyone,

 

I am trying to parse some XML for relevant info using firstChild, lastChild, and nextSibling.  For instance, given an XML file like...

 

<Item>
  <ItemID>110000579339</ItemID>
  <Site>US</Site>
  <Title>Halo 2 (Xbox)</Title>
  <Currency>USD</Currency>
  <SiteHostedPicture>
    <GalleryType>http://somesite.com/somepicture.jpg</GalleryType>
  </SiteHostedPicture>
  <PaymentMethods>PayPal</PaymentMethods>
</Item>

 

...when I try to get the ItemID, I just go xml_object.firstChild.firstChild.  But, when I try and get things from the bottom, I would have to go something like xml_object.firstChild.firstChild.firstChild.firstChild.firstChild.firstChild.firstChild (which would give me PaymentMethods...I think).  I could use xml_object.lastChild.firstChild, but that's not the point.  I would just like to know if there is an alternative to this sort of accessing of the XML fields?

 

My main concern is that for some XML files, the structure is slightly different (i.e. the <Site></Site> tags are not there).  So, the long call to access PaymentMethods for one XML file would not work on another.  Rather, it would return SiteHostedPicture for those.  Any help would be great.

 

Thanks

 

Charles
