Actually I know that there is Test::Valgrind::Parser::XML perl module. But I have no idea how to use it: If anyone can provide documentation it would be great.
The valgrind docs show that valgrind accepts a --xml=yes tag to output messages as XML. The format of the XML is specified in the docs/internals/xml-output-protocol4.txt inside the source code repository.
With that, you can use any XML parser and do whatever you want with the data.

I have a nunit3 result file, I need to parse and see if the format is right. I tried with nunit-console, does not have an parser option. How can i do the parse?
Either use a tool that can parse it or write your own.
A web search for a "NUnit Results Viewer" should give you some choices for existing tools.
You can see the format spec here:

I am creating XML data in Perl by using XML::LibXML Module But when i am writing the data into a file want to Pretty-printing it so that is it can be easily readable .
Below is a snapshot how i am creating xml from my perl script:
my $xml = XML::LibXML::Document->new('1.0', 'UTF-8');
$xml->createElement('A');
$elem->setAttribute('B',data)
Is there any way we can format the XML by using XML::LibXML because i have to stick with this module only.
The method XML::LibXML::Document::serialize writes the xml document as text. Its parameter allows for limited control over the format of the output.
XML::LibXML is a veneer to the libxml2 system library. This library comes with a hard-coded indentation of 2 spaces, so unless you create your own pretty-printer your options will be limited.
However, there are a number of standalone utilities that reformat syntactically valid xml and allow more fine-grained control and which can be run as a postprocessor from within perl on a file with the serialized xml. I've been satisfied with xmlstarlet and xmllint.
Another question is whether you really want to invest many resources into the endeavour. If you need the human-readable version for debugging or out-of-order inspection only, loading the data into a browser like Chrome or Firefox may be enough - they run xml data through a very decent pretty-printer.
I am working on a file upload system that also parses the files that are uploaded and generates another file based on info inside the file uploaded. The files being uploaded as XML files. I only need to parse the first XML tag in each file and only need to get the value of the single attribute in the tag.
Sample XML:
<LAB title="lab title goes here">...</LAB>
I am looking for a good way of extracting the value of the title attribute using the Perl split function or using Regex. I would use a Perl XML parser if I had the ability to install Perl modules on the server I am hosting my code on, however I do not have that ability.
This XML is located in an XML file, that I am opening and then attempting to parse out the attribute value. I have tried using both Split and Regex to no luck. However, I am not very familiar with Perl or regular expressions.
This is he basic outline my code so far:
open(LAB, "<", "path-to-file-goes-here") or die "Unable to open lab.\n";
foreach my $line (<LAB>) {
my #pieces = split(/"(.*)"/, $line);
foreach my $piece (#pieces) {
print "$piece\n";
}
}
I have tried using split to match against title alone using
/title/
Or match against the = character or the " character using
/\=/ or /\"/
I have also tried doing similar things using regex and have had no luck as well. I am not sure if I am just not using the proper expression or if this is not possible using split/regex. Any help on the matter would be much appreciated, as I am admittedly a novice at Perl still. If this type of question has been answered elsewhere, I apologize. I did some searching and could not find a solution. Most threads suggest using an XML parsing Perl module, which I would if I had the privileges to install them.
"But I can't use CPAN" is a quick way to get yourself downvoted on the Perl tag (though it wasn't I who did so). There are many ways that you can use CPAN, even if you don't have root. In fact you can have your own Perl even if you don't have root. While I highly recommend some of those options, for now, the easiest way to do this is just to download some Pure Perl modules, and included them in your codebase. Mojolicious has a very small, but very useful XML/DOM parser called Mojo::DOM which is a likely candidate for this kind of process.
I am using the Perl XML::LibXML module to create XML files.
I am not able to add newlines to the output XML file.
Does anyone have any ideas?
You have said nothing about how you are producing the output, but have you looked at the second parameter to toFile?
Something like
$doc->toFile('myfile.xml', 1)
should help.
I'm doing an app which can parse XML files generated from different programs. I need to check the first line of the file to detect which program has generated the xml and call the correct method to parse it.
i.e one of the file generated starts with this line:
<PROFILE XYZ="1">
another program generates the file starting with this line:
<AppXYZ DBVersion="1.2.3.4">
I need to check this line.
Any help is appreciated.
Thanks,
Max
It's XML, so just parse it as XML. Check the first element and decide from there. SAX or DOM, either works.
