How to count occurences...

[Rita_Ruah]

Hello, I have a programming doubt... I think this can apply to every language, imagine this scenario where I have this xml:

 

<MediaFiles>

<MediaFile>

   <![CDATA[VIDEO]]>

</MediaFile>

<MediaFile>

   <![CDATA[VIDEO]]>

</MediaFile>

<MediaFile>

   <![CDATA[VIDEO]]>

</MediaFile>

<MediaFile>

   <![CDATA[VIDEO]]>

</MediaFile>

<MediaFile>

   <![CDATA[VIDEO]]>

</MediaFile>

</MediaFiles>

 

How can I count the number of occurences of <MediaFile> so I can make a group of every mediafile and do a Random to select one of them?

 

Pseudo-code of what I want:

 

foreach(<mediafile> of <mediafiles>)

array[] = mediafile VIDEO;

 

Can you give me an example of php and other for JS? 

 

Thanks.
