Summary: simpleXML thinks that comment is node
Status: Open
Type: Feature/Change Request
Package: SimpleXML related
Operating System: *
PHP Version: 5.2.5
Block user comment: N
Private report: N
New Comment:
The best solution I can think of is to put comments into the pseudo-array returned by
SimpleXMLElement::children() with the same convention as attributes (with the key
"@attributes"). Comments should be represented by the key "@comments" in the
parent's children.

I see that my $xml simplexml object I can see the comments blocks but how do I
access and read them? Can I modify/insert comments into the xml somehow?
this is a print_r section:
[comment] => Array
(
[0] => SimpleXMLElement Object
(
)
[1] => SimpleXMLElement Object
(
)
[2] => SimpleXMLElement Object
(
)
[3] => SimpleXMLElement Object
(

[4] => SimpleXMLElement Object
(

[5] => SimpleXMLElement Object

[6] => SimpleXMLElement Object

[7] => SimpleXMLElement Object

It seems that the individual who reported this does not like this behaviour but I actually want
access to comments. [I'm managing Google Earth kml files and...well the detailed explanation is
lengthy].
Unfortunately the current behaviour doesn't seem to satisfy either of us because while comments
appear as nodes I can't seem to get access to their content. At the risk of disturbing the
peace of the purists, might I suggest something along the lines that if a comment is placed and
formatted like a node on a separate line -- eg:
<node>
<!-- comment -->
<a />
</node>
That it appear as a node (->node->comment) with a value with accessible content, but if placed
on another line it is simply ignored.
<node> <!-- this is ignored -->
I can hear the complaints already but what I'm really trying to suggest is some solution with a
bit of imagination where a comment can be identified as such and its value obtained.
<node <!--

SimpleXMLElement->children() do not think so !!! where is the TRUE ?
exsample:
<?php
$string = <<<XML
<?xml version='1.0'?>
<document>
<node>
<!-- comment -->
<a />
</node>
</document>
XML;
$xml = simplexml_load_string($string);
var_dump($xml->node);
$i = 0;
foreach ($xml->node as $node)
{
$i++;
}
echo $i . "\n";
var_dump((array) $xml->node);
$i = 0;
foreach ((array) $xml->node as $node)
{
$i++;
}
echo $i . "\n";
var_dump($xml->node->children());
$i = 0;
foreach ((array) $xml->node->children() as $node)
{
$i++;
}
echo $i . "\n";

>The comment is a node.
comment isn't node, it's nothing
exsampe:
<node></node> - node with empty value
<node><!-- comment --></node> - node with empty value
<node><!-- comment --> </node> - but not empty node thats has value
"space"
in :
>$i = 0;>foreach ((array) $xml->node as $node)>{> $i++;>}>echo $i . "\n";
he we checks child nodes, but not checks that node exists
see one more test:
<?php
$string = <<<XML
<?xml version='1.0'?>
<document>
<node><!-- comment --></node>
<otherNode></otherNode>
<comment>value</comment>
</document>
XML;
$xml = simplexml_load_string($string);
$i = 0;
foreach ((array) $xml->node as $node)
{
$i++;
}
echo $i . "\n";
$dom= new DOMDocument();
$dom->loadXML($string);
$Xpath = new domxpath($dom);
$NodeList = $Xpath->query('/document');
foreach ($NodeList as $Node)
{
foreach ($Node->childNodes as $cNode)
{
echo 'Name: ' . $cNode->nodeName . ' Value: ' . $cNode->nodeValue .
PHP_EOL;
if ($cNode->childNodes->length > 1) echo 'Has childNodes' . PHP_EOL;
}
}

The comment is a node. What we actually need is a way to figure out the xml type of a
SimpleXMLElement instance (Element, Comment,...). This will also have to return the internal SXE
state (iterator for something or direct value).
