[Tclxml-users] How to parse a particular tag in an XML document using TCLXML

[Kala V. <kv...@ci...>]

Hi,

	I need to parse the xml document using a TCL Function, by passing a tag 
name to retrieve the value of the tag. Something similar to "Simple.pm" in 
perl.  For example i have an example xml document :

<Outer>
	<Inner>
		Testing
	</Inner>
</Outer>
<Another>
	AnotherTag
</Another>

	Say to retrive the value contained in the tag "Another", i should pass 
"Another" to a TCL function, which should retreive me "AnotherTag". How can 
i use TCLXML to implement this?

	Moreover, i tried to run the flatten.tcl with the sample xml file given in 
the examples, it is giving an error. The error is as follows :

emch-sp22-ultra# tclsh8.3 flatten.tcl REC-xml-20001006.xml
can't read "config(wantElementDecls)": no such variable
     while executing
"if {$config(wantElementDecls)} {
         $parser configure -elementdeclcommand [list ElementDeclaration $out]
     }"
     (procedure "Process" line 13)
     invoked from within
"Process [read $ch] [expr {[file extension $filename] == ".dtd" ? "dtd" : 
"xml"}] stdout -baseurl file://[file join [pwd] $filename]"
     ("foreach" body line 6)
     invoked from within
"foreach filename $argv {
             if {$filename == "-"} {
                 Process [read stdin] xml stdout
             } else {
                 set ch [open $filename]
                 Process [read $ch] [..."
     ("default" arm line 2)
     invoked from within
"switch [llength $argv] {
     0 {
         if {![catch {package require Tk}]} {
             # Create a nice little GUI
             array set config {wantElementDecls 1 wantP..."
     (file "flatten.tcl" line 270)
emch-sp22-ultra#


	Can you let me know what the problem is? Is there any detailed 
documentation for TCLXML implementation?

Thanks in Advance,
