Examples

Get a list of the all the child nodes of an xml_node

This example uses the [xml->childNodes] method to drill down into the first child node of the XML node "month" to retrieve the node containing the last day of the month. Notice the indexing that is used in the [xml_nodeList->item] method to retrieve the desired xml_element.

Code

var(aMonth = xml('<month>
    <data>
        <name>March</name>
        <date type="lastDay">31</date>
    </data>
    <date>4</date>
    <date>11</date>
    <date>16</date>
    <date>23</date>
    <date>30</date>
</month>') )

'The child nodes are: \n'+$aMonth->childNodes()+'\n\n'

var( theMonth = $aMonth->childNodes->item(0) )

'The Month is: \n'+$theMonth+'\n\n'

var( lastDay = $theMonth->childNodes->item(1) )

'The lastDay is '+$lastDay

Result

The child nodes are: 
xml_nodeList(<data>
  <name>March</name>
  <date type="lastDay">31</date>
</data>, <date>4</date>, <date>11</date>, <date>16</date>, <date>23</date>, <date>30</date>)

The Month is: 
<data>
  <name>March</name>
  <date type="lastDay">31</date>
</data>

The lastDay is <date type="lastDay">31</date>
