When I went into command-line and tried it (again I'm using HP-UX
apparently):
[quote]
set php
<?
error_reporting(E_ALL & ~E_NOTICE);
$xml = preg_replace('/(>)[\\n\\r\\\s\\t]+(<)/', '$1$2',
$argv[1]); /* STRIP OUT WHITESPACE xml_parser_set_option() MIGHT MANGLE
XML */
$parser = @xml_parser_create();
@xml_parse_into_struct($parser, $xml, $xmlArray, $tags);
@xml_parser_free_parser($parser);
for ($i = 1; $i < @sizeof($xmlArray) - 1; $i++) \{
foreach ($xmlArray[$i]['attributes'] as $attr => $val)
$tclList .= $attr . ' \{' . str_replace('\{', '{',
str_replace('\}', '}', $val)) . '\} '; /* ESCAPED CURLY BRACES FOR
TCL LIST */
\}
echo trim($tclList);
?>
% exec /usr/local/bin/php -q << $php
<br />

I realize I am getting PHP errors, so at this point I don't know if
this is a TCL problem with the way I'm creating $php, or a PHP problem
with the way TCL handles PHP. So I believe cross-posting is essential
for this to be solved at this point.

Yes, but I was assuming that I needed to encase $php in single quotes
not for TCL exec but for the shell statement that is served by TCL
exec, if that makes sense.
