Copy characterdata from XML file to XML file

Hi,

I'm writing a Perl script that has to copy a block of data (nodes numbers
and coordinates) from one XML formatted file into another XML file.
I'm using XML::parser to extract the data and XML::Writer to write the
data into the second file.

This does not work, since some of the numbers are corrupted after being
read by XML::parser. Below I have copied a small bit that shows how the
data is corrupted. It always happens at the same line(s) of data.

My Perl script (I am not an experienced Perl programmer) is shown below.
The error occurs in the sub 'ReadCharacterData'. In this subroutine the
data is read and copied into a hash %tables. When writing this hash in the
output file the error shown above is found.

If anyone has an idea, or needs more info, please reply.

Be aware that character data, as also stated in the documentation, is
*not* available in your handler in one big string. The handler might get
called several times. A quick glance showed me that you're not aware of
this / not doing it right. What you should do:

if an start element is found: reset the global string buffer
if char data is found: glue it to the global buffer
if an end element is found, process the global string buffer

I agree with John Bokma. You have to have the start and end handlers as

I have to agree with John Bokma, get a better strategy
for capturing content data. Separate the processing
from the event handling as much as possible.
You can't rely upon parsing, nor the parser to
return content as in the source form. And you can't
really tell where content data begins and ends
without processing start and end events as well.

Print out the xml with indents so you can visually
see what is being sent to the handlers. A form
like this may help -

my $RD_xml = '';
my $last_content = '';
my $RD_xml = '';
my $special_tag = 0;

sub default_start_handler
{
my ($p, $element, %atts) = @_;
$element = uc($element);
$last_content = '';

## Check for start of singular tag data capture
## -----------------------------------------------
if ($element eq 'SPECIAL_TAG_ELEMENT')
{ $special_tag = 1; }

## Check for start of XML chunk data capture
## -----------------------------------------------
if ($element eq 'CAPTURE_ALL_OF_ME') {
$RD_xml = '';
$capturing_Is_part_of_larger_xml = 1;
}
if ($capturing_Is_part_of_larger_xml)
{ $RD_xml .= $p->original_string; }
}

sub default_content_handler
{
my ($p, $str) = @_;

## Use original for entities, incase reparse
## --------------------------------------------
$str = $p->original_string;

## Remove leading/trailing space, newline, tab
## if you want to do this now....
## -----------------------------------------------
$str =~ s/^[\x20\n\t]+//; $str =~ s/[\x20\n\t]+$//;

## Capture what is necessary. Last content is
## always captured by default
## -----------------------------------------------
if (length ($str) > 0) {
$last_content .= $str;
$RD_xml .= $str if ($capturing_Is_part_of_larger_xml);
}
}

sub default_end_handler
{
my ($p, $element) = @_;
$element = uc($element);

## Handle singular capture of special tag data

The error occurs in the sub 'ReadCharacterData'. In this subroutine the

If anyone has an idea, or needs more info, please reply.

I have to agree with John Bokma, get a better strategy
for capturing content data. Separate the processing
from the event handling as much as possible.
You can't rely upon parsing, nor the parser to
return content as in the source form. And you can't
really tell where content data begins and ends
without processing start and end events as well.

Print out the xml with indents so you can visually
see what is being sent to the handlers. A form
like this may help -

my $RD_xml = '';
my $last_content = '';
my $RD_xml = '';
my $special_tag = 0;

sub default_start_handler
{
my ($p, $element, %atts) = @_;
$element = uc($element);
$last_content = '';

## Check for start of singular tag data capture
## -----------------------------------------------
if ($element eq 'SPECIAL_TAG_ELEMENT')
{ $special_tag = 1; }

## Check for start of XML chunk data capture
## -----------------------------------------------
if ($element eq 'CAPTURE_ALL_OF_ME') {
$RD_xml = '';
$capturing_Is_part_of_larger_xml = 1;
}
if ($capturing_Is_part_of_larger_xml)
{ $RD_xml .= $p->original_string; }
}

sub default_content_handler
{
my ($p, $str) = @_;

## Use original for entities, incase reparse
## --------------------------------------------
$str = $p->original_string;

## Remove leading/trailing space, newline, tab
## if you want to do this now....
## -----------------------------------------------
$str =~ s/^[\x20\n\t]+//; $str =~ s/[\x20\n\t]+$//;

## Capture what is necessary. Last content is
## always captured by default
## -----------------------------------------------
if (length ($str) > 0) {
$last_content .= $str;
$RD_xml .= $str if ($capturing_Is_part_of_larger_xml);
}
}

sub default_end_handler
{
my ($p, $element) = @_;
$element = uc($element);

## Handle singular capture of special tag data
## ---------------------------------------------
if ($element eq 'SPECIAL_TAG_ELEMENT') {
ProcessContent ($last_content) if ($special_tag);
$special_tag = 0;
}
$last_content = '';

Hi,

I'm writing a Perl script that has to copy a block of data (nodes numbers
and coordinates) from one XML formatted file into another XML file.
I'm using XML::parser to extract the data and XML::Writer to write the
data into the second file.

This does not work, since some of the numbers are corrupted after being
read by XML::parser. Below I have copied a small bit that shows how the
data is corrupted. It always happens at the same line(s) of data.

I agree with John Bokma, you need the start and end handlers as well.
Something like this --

my $RD_xml = '';
my $last_content = '';
my $RD_xml = '';
my $special_tag = 0;

sub default_start_handler
{
my ($p, $element, %atts) = @_;
$element = uc($element);
$last_content = '';

## Check for start of singular tag data capture
## -----------------------------------------------
if ($element eq 'SPECIAL_TAG_ELEMENT')
{ $special_tag = 1; }

## Check for start of XML chunk data capture
## -----------------------------------------------
if ($element eq 'CAPTURE_ALL_OF_ME') {
$RD_xml = '';
$capturing_Is_part_of_larger_xml = 1;
}
if ($capturing_Is_part_of_larger_xml)
{ $RD_xml .= $p->original_string; }
}

sub default_content_handler
{
my ($p, $str) = @_;

## Use original for entities, incase reparse
## --------------------------------------------
$str = $p->original_string;

## Remove leading/trailing space, newline, tab
## if you want to do this now....
## -----------------------------------------------
$str =~ s/^[\x20\n\t]+//; $str =~ s/[\x20\n\t]+$//;

## Capture what is necessary. Last content is
## always captured by default
## -----------------------------------------------
if (length ($str) > 0) {
$last_content .= $str;
$RD_xml .= $str if ($capturing_Is_part_of_larger_xml);
}
}

sub default_end_handler
{
my ($p, $element) = @_;
$element = uc($element);

## Handle singular capture of special tag data
## ---------------------------------------------
if ($element eq 'SPECIAL_TAG_ELEMENT') {
ProcessContent ($last_content) if ($special_tag);
$special_tag = 0;
}
$last_content = '';

## Handle larger capture XML chunks
## -----------------------------------
if ($element eq 'CAPTURE_ALL_OF_ME') {
if ($capturing_Is_part_of_larger_xml) {
$RD_xml .= $p->original_string;
ProcessXmlChunk ($RD_xml);
}
$RD_xml = '';
$capturing_Is_part_of_larger_xml = 0;
}
}

I assume your side, because I didn't even see a single one.
