This xml comes from a PHP script, writing into a XML file and this is the
content of the XML file with an ASCII editor.

Ok, so I would like to set a ISO-8859-1 header but the PHP XML API creating
a XML file doesn't let me to parameter this but only XML version (APIs are
xmldoc, domxml_new_xmldoc)... This is the PHP code creating the XML file:

// retrieves form's submitted data reconstructed into bound document
        function get_submit($document="", $errors="")
                global $HTTP_POST_VARS;

                if ($document)
                        $doc = xmldoc($document);
                        $doc = domxml_new_xmldoc("1.0");

//              $formdoc = xmldocfile($this->definition);
                $formdoc = xmldoc(load_file($this->definition));
                $formctx = xpath_new_context($formdoc);

                $result = xpath_eval($formctx, "//field[@binding and (@display = 'edit' or
not(@display)) and @control != 'label' and @control != 'readonly']");
                foreach ($result->nodeset as $node)
                        $value = $HTTP_POST_VARS[$node->get_attribute("name")];
                        if ($node->get_attribute("required") == "true" && !$value)
                                $errors[] = $node->get_attribute("label")." field is required";
                        if ($node->get_attribute("pattern")
&& !ereg($node->get_attribute("pattern"), $value))
                                $errors[] = $node->get_attribute("label")." does not match pattern";
                        put_xpath($doc, $node->get_attribute("binding"), $value);
                $root = $formdoc->root();
                foreach ($root->children() as $node)
                        if ($node->tagname == "field")
                                put_xpath($doc, $node->get_attribute("binding"),
                return $doc->dumpmem();

I saw dumped could take no documented parameters to select other UTF
encoding. So I modified the last line:

                return $doc->dumpmem(0,"ISO-8859-1");

1. The dumpem warmed...

3. It's relaod with Sablotron failed...

What do you think of this?
