Iterating through an xml with prompts

[bhairav]

As part of the http response using the data tag, I receive an xml like

<Addresses>
<entry>205 W LAUREL ST, Glendale</entry>
<entry>20261 E COVINA BLVD, Charter Oak</entry>
<entry>201 E MAGNOLIA BLVD, Burbank</entry>
<entry>2010 ZONAL AVE, Los Angeles</entry>
<entry>2000 W EMPIRE AVE, Burbank</entry>
</Addresses>

The no of entry elements is dynamic.

At IVR interface, I need to iterate these entries to choose one of them

Like
Press 1 for "205 W LAUREL ST, Glendale"
Press 2 for "20261 E COVINA BLVD, Charter Oak"
Press 3 for
....

I have looked into foreach tag, but how do I keep track of the count 1, 2, 3...


Please advise.

You will have to use another programming language, like PHP, to dynamically generate menus. You should POST the XML to a .PHP page using the <submit> tag. Then you must parse your XML and generate VXML grammar and prompts. You can echo those out via PHP. Here is an example:

Code: Select all

<?php 
$addresses = $_POST['address_xml']; // Get addresses XML from POST
// Do some string manipulation here on the XML to make $addresses an array of your addresses

$address_grammar = 
  '<grammar type="application/srgs+xml" root="addresses" mode="dtmf">
    <rule id="addresses">
      <one-of>';

$address_prompt = '';

// Loop for each address to add to $address_grammar and $address_prompt
foreach ($addresses as $i => $address) {
  // Add grammar info
  $address_grammar .= '<item>' .  $i+1 . '<tag>address="' . $address . '"</tag>';

  // Add to address prompt
  $address_prompt .= 'Press ' . $i+1 . ' for ' . $address;
}

$address_grammar .= '</one-of></rule></grammar>';

header('Content-type: text/xml');  
?>

<?xml version="1.0"?>
<vxml version="2.0">
  <form id="get_address">
    <field name="address">
      <?= $address_grammar ?>

      <prompt> <?= $address_prompt ?> </prompt>

      <filled>...</filled>
    </field>
  </form>
</vxml>
