[RESOLVED] XML_ERR_NAME_REQUIRED issue

druidmatrix

From my reserach on the Net (php.net does not seem to have any info on this), it seems this error is mostly due to unacceptable characters ('&' being the main suspect I believe) in the XML document being parsed. But I have a strange problem with a simple XML Document that I cannot debug. The following lines of code are responsible:

$parser = xml_parser_create('');
xml_parser_set_option($parser,XML_OPTION_SKIP_WHITE,1);
$suc = xml_parse_into_struct($parser,$ret,&$val,&$index);
if (!$suc)
	self::logIt("got an error parsing \n$ret\n:".xml_error_string(xml_get_error_code($parser)));
xml_parser_free($parser);

The corresponding log entry is:

07 Jan 2010 01:32:45: got an error parsing
<?xml version="1.0" encoding="UTF-8"?>
<array>
<1>platinum</1>
<2>gold</2>
<3>value</3>
</array>

:XML_ERR_NAME_REQUIRED

The Soap response the above XML came from is is:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://172.16.0.200/webservices" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV:Body><ns1:getCustSlaDescsResponse><return xsi:type="xsd:string"><?xml version="1.0" encoding="UTF-8"?>
<array>
<1>platinum</1>
<2>gold</2>
<3>value</3>
</array>
</return></ns1:getCustSlaDescsResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>

Any pointers would be highly appreciated!!

[RESOLVED] XML Parser Error: XML_ERR_NAME_REQUIRED

I dont believe the "&" character is a valid character in XML, without using CDATA tags.

But there are no '&' or other unacceptable characters in the xml as the log entry shows:

07 Jan 2010 01:32:45: got an error parsing
<?xml version="1.0" encoding="UTF-8"?>
<array>
<1>platinum</1>
<2>gold</2>
<3>value</3>
</array>
:XML_ERR_NAME_REQUIRED

Any other suggestions?

1 isn't a valid name for a tag. Nor are 2 and 3.

http://www.w3.org/TR/REC-xml/#sec-starttags

The first character of a Name MUST be a NameStartChar, and any other characters MUST be NameChars; this mechanism is used to prevent names from beginning with European (ASCII) digits or with basic combining characters. [emphasis mine]

Absolutely correct Weed!!! From http://www.xml.com/pub/a/2001/07/25/namingparts.html regarding the XML tag names:

[4] NameChar ::= Letter | Digit | '.' | '-' | '' | ':' | CombiningChar | Extender
[5] Name ::= (Letter | '' | ':') (NameChar)*

Thank you Sir!!!
