My TCL proc, XML_GET_ALL_ELEMENT_ATTRS, is supposed to convert an XML
file into a TCL list as follows:

attr1 {val1} attr2 {val2} ... attrN {valN}

This is the TCL code that does this:

[TCL]
set contents [read $fileID [file size ${fileName}.xml]]; close $fileID


if {![string equal $switch -body]} {
# ONLY DO THIS IF THE XML CONTENTS CONTAIN NO BODY - WILL UPGRADE AT
A LATER DATE 11/24/2006 - PHIL
global serverName
if {![info exists serverName]} {
global env
source ./cgi_globals.tcl
global serverName
}

if {[string length [info procs {URL_ENCODE}]] == 0} { source
../url_procs.tcl }; # INCLUDE NEW url_procs.tcl URL TCL LIBRARY
if {[string length [info procs {IS_LIST}]] == 0} { source
{./tcl_string_tools.tcl} }; # INCLUDE THE TCL STRING LIBRARY CONTAINING
PROC is_list IF !FOUND

# BLOCK TO CREATE THE PHP SCRIPT TO PIPE INTO php.exe
regsub -all {'} [XML_CLEANUP_ATTRIBUTE $contents] {\"}
phpEscapedContents
regsub -all {"} $phpEscapedContents {\"} phpEscapedContents
set php {<? }
append php [subst { if (@is_file("./functions.inc.php")) [format %c
123] }]
append php { require_once("./functions.inc.php"); }
append php [subst { echo xml_to_tcl_list("$phpEscapedContents"); }]
append php [subst {[format %c 125] }]
append php { ?>}


set cannotRunPHP [catch {exec "echo '$php' | php" >@stdout
2>&stderr} errorMsg]
if {$cannotRunPHP} {
puts $errorMsg
return {}
} else {
if {![IS_LIST $contentsList]} { set contentsList [split
$contentsList] }
if {[llength $contentsList] == 0} { lappend contentsList {?} }
return [lrange $contentsList [expr {[lsearch -exact $contentsList
"?"] + 1}] end]
}

}
[/TCL]

The command-line PHP should look like this:

[PHP]
<? if (@is_file("./functions.inc.php")) {
require_once("./functions.inc.php"); echo
xml_to_tcl_list("$phpEscapedContents"); } ?>
[/PHP]

Note that $phpEscapedContents is a TCL variable, not a PHP variable

Ok, so this is what should happen:

1) PHP function xml_to_tcl_list will convert the inputted escaped XML
string into a TCL list
2) I need to return that TCL list into $contentsList and return it so
the proc returns a TCL list

However, it never gets that far, here is the error I get:

[quote]
couldn't execute "echo '<? if (@is_file("./functions.inc.php")) {
require_once("./functions.inc.php"); echo xml_to_tcl_list("&lt;?xml
version=&quot;1.0&quot; encod": file name too long
[/quote]

I am sure I am going at this the wrong way, but I can't understand the
right way (TCL DOM parsing is far FAR beyond my ability to understand,
I've read manuals, tutorials, books, to no avail: I simply don't
understand how TCL can ever parse XML, I only understand simple PHP
parsing XML)

So at this point, all I want to do is convert an XML string into a TCL
list, and the only way I know how to do it is via PHP, but I can't get
all three languages to cooperate.

Help appreciated.

Thanx
Phil
