Replacing Existing DCR Node with New String.

vinitsmore

Hi All,

I am working on XML parsing through perl. I am trying to replace existing Node with new values.

XML structure is similar to below

I want to replace existing structure with new format. (refer to New_Format)

I have information under object_details node in a variable. I am using perl.

Now I want to set it to existing node.. so that it replaces old values and add new values also.

I tried to use following
1) $rootnode->set_inner_xml('object_details.object_desc_cont', $new_object_desc_cont );

2) $result = $rootnode->set_node_list('object_details', $new_object_desc_cont);
if (!defined $result){
print LOG "Something Wrong.. \n" if $debug;
}

Bot no luck..!!

Can please someone help..

you need to post all of you code to find the probelm... but why don't you just use regex to replace / add text in the DCR file?

Hi..

Please find the attached file.. with my code.

Can you also please give me some example of how to use regex and replace existing node with new node structure and values.

Thanks

In "XML-like" substitution it is safer to do "non-greedy" Match. Your version *may* replace too much if there are
several "replace_me" Tags - which is not the case in the sample Smiley Happy

$xml_string =~ s|<replace_me>.*?</replace_me>|$new_xml|sm;
(Without 'g' modifier that'll get the first or the only one)

I have replaced existing XML with new XML, but when I open a new DCR, it doesnt show values for some existing fields

For e.g
In DCR, I have a Text field -- object_desc_item

In DCR XML, values is present.. but it is not reflected in DCR field.

Please find attached the code(line 204-221) and Modified and Old XML file.

Chances are, your modified DCR does not conform to the new DCT. To test your script start small.

Create and Save both old and new style DCRs from GUI. Use as much identical User input as possible.
Convert the old one using your script. Compare the result to the TS created "new" DCR and see what differs.
Fix code and repeat

When you're re-inserting text, especially for textarea fields, you have to make sure that the contents of the text are re-entitized (for lack of a real word). For instance (code formatted with indenting), in the OLD DCR I see:

...
      <object_desc_item>
          &lt;p&gt;&lt;strong&gt;Can I apply directly to one of Monitor's business units?&lt;/strong&gt;&lt;br /&gt;
          ...
      </object_desc_item>
...

but in the NEW DCR I see:

...
        <object_desc_item>
          <p>
            <strong>Can I apply directly to one of Monitor's business units?</strong>
             ...
         </object_desc_item>
...

Thus, in the new DCR, the structure has changed because there are now 'p' and 'strong' containers, etc.

Take a look at perldoc HTML::Entities for help on resolving this.

(PS: Thanks Boris for the non-greedy fix, I neglected to think of that at the time I threw together a quick demo)
