I know this may be a newbie question, but please humor me. When reading an xml string with "soap:" in the tags, simplexml_load_string() will not read in the xml.
given this script:
#!/usr/bin/php
<?php
$s='
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<soap:Header>
<context xmlns="urn:zimbra"/>
</soap:Header>
<soap:Body>
<AuthResponse xmlns="urn:zimbraAdmin">
<authToken>somevalue</authToken>
<lifetime>123124123</lifetime>
<a n="zimbraIsDomainAdminAccount">false</a>
</AuthResponse>
</soap:Body>
</soap:Envelope>';
print_r(simplexml_load_string($s));
echo "\n\n";
print_r(simplexml_load_string(str_ireplace("soap:", "", $s)));
?>
I get this output:
jesse@jesse-debian:~/code/zmsoap$ ./xmltest.php
SimpleXMLElement Object
(

SimpleXMLElement Object
(
[Header] => SimpleXMLElement Object
(
[context] => SimpleXMLElement Object
(
)
)
[Body] => SimpleXMLElement Object
(
[AuthResponse] => SimpleXMLElement Object
(
[authToken] => somevalue
[lifetime] => 123124123
[a] => false
)
)
)

I'm just curious why this is happening, and if there is a more proper way to remedy the problem as opposed to doing a string replace.
A tag name with a colon in indicates the tag is in a non-default namespace. SimpleXML only looks at one namespace at a time, so you need to specifically select the namespace using the ->children()
method.
In this case $xml->children('http://www.w3.org/2003/05/soap-envelope')->Body
or $xml->children('soap', true)->Body
should both work.
For this and other reasons, it's not advisable to use print_r
to debug SimpleXML objects. Try this dedicated function instead.
