Chunk by Chunk processing of XML

[rellaboyina]

Need to process an XML Chunk by Chunk.....

I had an XML. It will consist of a number of similar type of tags and what I want to do is to process a certaing group of methods on each of these similar group of tags everytime.

I tried it out with XML::Twig. But not able to get it as I am new to Perl.

Can anybody help me out in this please.....

Eg:
<tsip:dataFeed= ....>
<tsip><inventio n>.....</invention></tsip>
<tsip><inventio n>.....</invention></tsip>
<tsip><inventio n>.....</invention></tsip>
</tsip:dataFeed>

Now what I want to do is , to process each <tsip></tsip> element using some methods which are user-defined.

Do you have this same question on another forum? Has it recieved any replies if you do?

Try something like this:

$tag = "tsip";

@lines = (
  "<tsip:dataFeed=....>",
  "<tsip><invention>.....</invention></tsip>",
  "<tsip><invention>.....</invention></tsip>",
  "<tsip><invention>.....</invention></tsip>",
  "</tsip:dataFeed>",
);

sub userDefinedMethod {
  my($content) = @_;

  printf("$content\n");
}

for $line ( @lines ) {
  if ( $line =~ m(^<$tag>(.*)</$tag>$) ) {
    userDefinedMethod($1);
  }
}

Till now I haven't recieved any replies for this query. Can u help me out please?

[KevinADC]

did you read the suggestion posted by doc?

[rellaboyina]

I have tried with what Mr.doc has suggested. But it will not fulfill my purpose.

For that what I was doing is, I have taken the module XML::Twig, and parsing the file using the xpaths of the required tags, attributes and the elements.

But to process each <tsip> what I was doing is that, creating a separate xml file for each tsip and parsing that which will ultimately result in the more memory consumption.

So I would like to know that whether there is any process of parsing the xml file without following the process which I did and taking the less memory.

[KevinADC]

I'm sure there is but it's something I have no practical experience with. There are a lot of XML modules, maybe one of the other ones will work for you:

XML::XPath or XML::LibXML

[rellaboyina]

I have already tried with XML::XPath. But the module XML::Twig is giving the best performance when compared to XML::XPath. So can you please help me out in this?
