[RESOLVED] simplexml error

vertmonkee

I'm parsing an xml document using simplexml and I'm receiving an error which I just can't find solution to despite a lot of searching and reading.

These are the first few line of my xml document

<?xml version="1.0" encoding="utf-8"?>
<MD_Metadata xmlns="http://www.isotc211.org/2005/gmd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:gco="http://www.isotc211.org/2005/gco" xmlns:gmd="http://www.isotc211.org/2005/gmd" xmlns:gml="http://www.opengis.net/gml" xmlns:xlink="http://www.w3.org/1999/xlink" xsi:schemaLocation="http://www.isotc211.org/2005/gmd http://www.isotc211.org/2005/gmd/gmd.xsd">
 <fileIdentifier>
  <gcoCharacterString>beemsa5e1453e-8f0f-429c-85b3-e307cc4a065d</gcoCharacterString>
 </fileIdentifier>

All I am trying to do to start with is echo out the beemsa5e1453e-8f0f-429c-85b3-e307cc4a065d in the gcoCharacterString

My code so far has been

$importxml = simplexml_load_string($xml_file);

echo $fileIdentifier = $importxml->MD_Metadata->fileIdentifier->gcoCharacterString;

But this gives the error

Notice: Trying to get property of non-object in C:\Program Files\Apache Group\Apache2\htdocs\display_xml.php on line 14

Thanks for any help and suggestions.

Try this:

$importxml = simplexml_load_string($xml_file);
$ns_arr = $importxml->getDocNamespaces();
foreach ($importxml->fileIdentifier as $fi) {
    $gco_ns = $fi->children($ns_arr['gco']);
    echo $gco_ns->CharacterString;
}

That hasn't worked but thanks for trying.

There shouldn't have been a colon in the closing tag of gcoCharacterString, I've edited the post above which now reads correctly.

Thanks

Installer

I assumed the colon did belong there, but forgot to point out that it was missing. If you're interested for future reference, the code I posted will work in cases like that.

This should work:

echo $fileIdentifier = $importxml->fileIdentifier->gcoCharacterString;

I just tried it with colons in and that works thanks.

But still no good without the colons.

Thanks for the help though.

Installer

You're welcome, though.

The first code I posted works fine for me, too, if the colons are there. The second code also works fine for me with your edited XML.

Excellent thanks for your help that is working perfectly now.
