In my script I find the number of children for the nearby airports which in this case will return 4. I then get a random number from 1 to the max of the number of children. If my script returns 3 how can I go about getting the ICAO from the 3rd airport from this group of airport stations which is KASW

Any Ideas on how to do this

Re: Retrieve a specific Node from XML

Take a look at revXMLChildNames. You can use that and then index (untested code, but I've used it before successfully, you may need to tweak what's below some):

Code: Select all

put revXMLRootNode(tTree) into tRoot
put revXMLChildNames(tTree, tRoot, "airport",true) into tAirport

revXMLNodeContents(tTree, tRoot & "/" & tAirport[1] & "/name") into tAirport_1
revXMLNodeContents(tTree, tRoot & "/" & tAirport[2] & "/name") into tAirport_2
revXMLNodeContents(tTree, tRoot & "/" & tAirport[3] & "/name") into tAirport_3

...
So, given the above, you should be able to easily use a random number to index into tAirport and grab all the data you need from it.

HTH,

Jeff M.

For my knowledge as I investigate this, does the Array start at 0 like it does within the flash environment?

Example would be Airport[0] would be the first item in the array
Airport[1] would be the second item in the array
etc.

Honestly, I don't remember, but I'd put money down on them starting at 1, given that everything else in Rev starts at 1. It wouldn't be too difficult to set a breakpoint and look inside the array and see. ;)

Re: Retrieve a specific Node from XML

I have this xml data that my boss wants uploaded/store to a mysql database:

Code: Select all

	<?xml version="1.0" encoding="UTF-8" standalone="no"?>
	<table> 
		<record>
			<id>100</id>
			<last_name>smith</last_name>
			<first_name>john</last_name>
			<country>usa</country>
		</record>
		<record>
			<id>200</id>
			<last_name>gates</last_name>
			<first_name>william</last_name>
			<country>usa</country>	
		</record>
		<record>
			<id>300</id>
			<last_name>mcdonald</last_name>
			<first_name>ronald</last_name>
			<country>japan</country>	
		</record>
		<record>
			<id>400</id>
			<last_name>chips</last_name>
			<first_name>fish</last_name>
			<country>uk</country>	
		</record>	
	</table>
I can't get the examples to work on this. I'm newbie to rev and not an xml expert either. I would appreciate any assistance on this or an example code would be nice.

You've got a few mismatched close tags there, so the XML library won't be able to form a tree for you.

Specifically, in each record, you've closed the <first_name> tag with a </last_name> tag.

<record>
<id>100</id>
<last_name>smith</last_name>
<first_name>john</last_name>
<country>usa</country>
</record>

Cheers,


Steve

Corrected the typo. Below is the php code that I wanted to convert to Rev:
<?php
$doc = new DOMDocument();
$doc->load( 'people.xml' );

$records = $doc->getElementsByTagName( record" );
foreach( $records as $record )
{
$last_names = $record->getElementsByTagName( "last_name" );
$last_name = $last_names->item(0)->nodeValue;

$first_names = $record->getElementsByTagName( "first_name" );
$first_name = $first_names->item(0)->nodeValue;

$countries = $record->getElementsByTagName( "country" );
$country = $countries->item(0)->nodeValue;

echo "$last_name - $first_name - $country\n";
}
?>

Re: Retrieve a specific Node from XML

I'd be inclined to do something like:

Code: Select all

function readxml pFilePath
    local tXMLTreeID
    local tRoot
    local tResponse
    local tChildNode
    local tID
    local aRecords
    
    put revCreateXMLTreeFromFile(pFilePath, false, true, false) into tXMLTreeID
    put revXMLRootNode(tXMLTreeID) into tRoot -- "table"
    put revXMLFirstChild(tXMLTreeID,tRoot) into tResponse -- "record"
    repeat while "xmlerr" is not in tResponse
        put revXMLNodeContents(tXMLTreeID, tResponse & "/id") into tID
        put revXMLNodeContents(tXMLTreeID, tResponse & "/last_name") into aRecords[tID]["lastname"]
        put revXMLNodeContents(tXMLTreeID, tResponse & "/first_name") into aRecords[tID]["firstname"]
        put revXMLNodeContents(tXMLTreeID, tResponse & "/country") into aRecords[tID]["country"]
        put revXMLNextSibling(tXMLTreeID,tResponse) into tResponse
        if tResponse is empty then
            exit repeat
        end if
    end repeat
    return aRecords
end readxml
if you pass this function a path to a file (as returned from an "answer file" command, for instance) it will return you an array (aRecords) with all your records neatly arranged by id. The php code looks a bit cleaner, but you're not doing any error checking and you're creating three separate arrays.

Re: Retrieve a specific Node from XML

Hello,

I have a somewhat similar question, so I post it here.
How do I get hold of the comments in an XML document?
revCreateXMLTree parses a document and gives you an ID to handle the resulting tree.
But I find no revXMLxxx() to get any comment text, but using revXMLText with the ID of the tree created by revCreateXMLTree, I do get the text back including the comments.

Have I overlooked something?
