How to Access XML Nodes with Hyphens in PHP?

XML Node Names with Hyphens in PHP

When attempting to extract data from XML using node names containing hyphens, a "Warning: Invalid argument supplied for foreach()" error may arise. This occurs due to PHP's naming convention restrictions.

To address this, the PHP manual recommends encapsulating such element names within braces and apostrophes. For instance, in your case, instead of:

foreach ($xml->custom-field-value as $milestone)
{
    ...     
}

You should write:

$xml->{'custom-field-value'}

This will allow you to access and iterate over elements with hyphenated node names seamlessly.
