Some help with limiting records from XML

[Kaanha]

Ok..I'm new to XML, but I've worked alot with mySQL and PHP so I understand the concepts that XML is using, I just don't know all the key terms and syntax and what not.

First, if I have an XML file with say 20 records and I only want to retrive the first 10, how can that be done, instead of returning all 20.

Second, with the same XML file if I want to move my pointer to Record 10 and retrive the next 5...how can that be done? (Basically I want to start my record pointer on record 10 instead of record 1 and grab the next 5).

I've done searchs but without knowing what things are called and having any idea of key words for XML or anything like that I'm at a bit of a lost on how to search for this.

All help is welcomed and I thnka everyone who helps me!

XML is not a database. It is structured data in the form of a string that uses tags to denote nodes.

The usual way to select node(s) from an XML file is using XPath:

http://www.w3schools.com/xpath/default.asp

XPath is used in within XSL stylesheets, or as part of DOM processing within a host programming language, such as PHP (which itself uses the sablotron XSLT extension functions to deal with XML).

The XPath to find the first 10 nodes and nodes 11-15 is simple:

mynode[position() < 11]

and

mynode[position() > 10 and position() < 16]

But to answer your question fully, we need to know what technologies you'll be using to process the XML.

I will be using PHP to process all my XML. Can you provide an example using PHP or a website that can provide an example? Thanks for all your help, I'm currently looking up the XPath and reading up on that.

Google for 'php xml dom'. This looks good:
