There needs to be a definition of the xsi namespace. E.g.
<ShowVehicleRemarketing
environment="Production"
lang="en-CA"
release="8.1-Lite"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.starstandards.org/STAR/STAR/Rev4.2.4/BODs/Standalone/ShowVehicleRemarketing.xsd"
>
Update: You could write a user defined filter and then let the XMLReader use that filter, something like:
stream_filter_register('darn', 'DarnFilter');
$src = 'php://filter/read=darn/resource=compress.zlib://something.xml.gz';
$reader->open($src);
The contents read by the compress.zlib wrapper is then "routed" through the DarnFilter which has to find the (first) location where it can insert the xmlns:xsi declaration. But this is quite messy and will take some afford to do it right (e.g. theoretically bucket A could contain xs, bucket B i:schem and bucket C aLocation=")
Update 2: here's an ad-hoc example of a filter in php that inserts the xsi namespace declaration. Mostly untested (worked with the one test I ran ;-) ) and undocumented. Take it as a proof-of-concept not production-code.
<?php
stream_filter_register('darn', 'DarnFilter');
$src = 'php://filter/read=darn/resource=compress.zlib://d:/test.xml.gz';
$r = new XMLReader;
$r->open($src);
while($r->read()) {
echo '.';
}
class DarnFilter extends php_user_filter {
protected $buffer='';
protected $status = PSFS_FEED_ME;
public function filter($in, $out, &$consumed, $closing)
{
while ( $bucket = stream_bucket_make_writeable($in) ) {
$consumed += $bucket->datalen;
if ( PSFS_PASS_ON == $this->status ) {
// we're already done, just copy the content
stream_bucket_append($out, $bucket);
}
else {
$this->buffer .= $bucket->data;
if ( $this->foo() ) {
// first element found
// send the current buffer
$bucket->data = $this->buffer;
$bucket->datalen = strlen($bucket->data);
stream_bucket_append($out, $bucket);
$this->buffer = null;
// no need for further processing
$this->status = PSFS_PASS_ON;
}
}
}
return $this->status;
}
/* looks for the first (root) element in $this->buffer
* if it doesn't contain a xsi namespace decl inserts it
*/
protected function foo() {
$rc = false;
if ( preg_match('!<([^?>\s]+)\s?([^>]*)>!', $this->buffer, $m, PREG_OFFSET_CAPTURE) ) {
$rc = true;
if ( false===strpos($m[2][0], 'xmlns:xsi') ) {
echo ' inserting xsi decl ';
$in = '<'.$m[1][0]
. ' xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" '
. $m[2][0] . '>';
$this->buffer = substr($this->buffer, 0, $m[0][1])
. $in
. substr($this->buffer, $m[0][1] + strlen($m[0][0]));
}
}
return $rc;
}
}
Update 3: And here's an ad-hoc solution written in C#
XmlNamespaceManager nsmgr = new XmlNamespaceManager(new NameTable());
// prime the XMLReader with the xsi namespace
nsmgr.AddNamespace("xsi", "http://www.w3.org/2001/XMLSchema-instance");
using ( XmlReader reader = XmlTextReader.Create(
new GZipStream(new FileStream(@"\test.xml.gz", FileMode.Open, FileAccess.Read), CompressionMode.Decompress),
new XmlReaderSettings(),
new XmlParserContext(null, nsmgr, null, XmlSpace.None)
)) {
while (reader.Read())
{
System.Console.Write('.');
}
}
