Re^2: Edit XML through XML Compile

Well i know generally a code example is helpfull, but i thought in this case its a pretty General question. Anyhow, I will give you some examples of what i am doing at the Moment. given is a Schema like :

-data
   -properties
     (List of properties in here)
-suites
   -tests
[download]

Up to now i got my code writing the properties.

$schema->template('PERL', $type); 
#warn $schema->template('PERL', $type);
 my $doc    = XML::LibXML::Document->new('1.0', 'UTF-8');
 my $write  = $schema->compile(WRITER => $type, use_default_namespace 
+=> 1);
 my %hash;
 #some filling of the hash with values
my $xml    = $write->($doc, $hash);
 $doc->setDocumentElement($xml);
[download]

So the first part of my XML File is generated. Later on, in a completely different part of the program, tests have to be written into the second section. Those tests have to comply the Schema in the xsd file. So i have to reopen the saved XML file from the code above and insert some new tags in it, at specific Points (every test has to go into a specific Suite, so there is more than one Suite) Writing a new hash and doing

my $xml    = $write->($doc, $hash);
 $doc->setDocumentElement($xml);
[download]

again, does not work out. I need to reopen, search a node and insert children. This was easy possible with XML Twig, but as said i can only use above mentioned packages. Was this enough code or do you Need more explaning?

General questions get general answers... there is an example of reading an XML file with XML::Compile in this article: http://perl.overmeer.net/xml-compile/papers/201208-PerlMagazine-article-en.html That gets you a Perl data structure which you can manipulate to add the items you need. If you're not sure how to go about that, then these should be helpful: perldsc, perlreftut, perlref An example of writing that back out is here: http://blogs.perl.org/users/brian_e_lozier/2011/10/using-xmlcompile-to-output-xsd-compliant-xml.html (note XML::LibXML::Document's `toFile` method is probably helpful) That gives you everything you need to do what you describe. For more specific answers, be more specific than "does not work out", for example provide a runnable sample program that reproduces the problem. I know what I mean. Why don't you?	[reply] [d/l]

Well, maybe does not work out wasn't the right choice of words, i am sorry for this. Yes, my question is as General as you answered it, but you seemed to got me wrong in one point. I have read overmeers article before i opened my thread. (I read the other two links previously too) In the section about writing, he explains how to insert a node in an existing file, DWIM style. Thats what i want to do, as working in the hashes seems to unreliable for me. Unfortunately, i haven't got XML::Compiler::Cache for use. So my question was about if there is any way to to it in this style but with only the modules given in my first post and without Messing aroung within the hashes. Even if there would be an easy way to get my XML File into an LibXML-Document and search for parents and add children in this would be enough for me, i think. Thas why i was asking for if there is any possibility in XML Compile to edit items in a style like in LibXML::Documents or XML:Twig	[reply]

Unfortunately, i haven't got XML::Compiler::Cache for use. I don't think you need XML::Compile::Cache to use XML::Compile. In the section about writing, he explains how to insert a node in an existing file, DWIM style. I think you may have misunderstood this in the article - he doesn't actually explain how to insert a node in an existing file; as far as I can tell the "DWIM" refers to the translation of the Perl data structure back to XML, not some other method of manipulating nodes. That is how XML::Compile works - it translates between XML and Perl data structures, applying all sorts of checks to make sure the translation is clean and the XML is valid. Thats what i want to do, as working in the hashes seems to unreliable for me. Not sure what you mean by "unreliable" - XML::Compile will translate your Perl data structure back to XML as cleanly as it can, and it guarantees to write valid XML. It seems like you're more worried about working with the hashes than you need to be... So my question was about if there is any way to to it in this style but with only the modules given in my first post and without Messing aroung within the hashes. Even if there would be an easy way to get my XML File into an LibXML-Document and search for parents and add children in this would be enough for me, i think. Thas why i was asking for if there is any possibility in XML Compile to edit items in a style like in LibXML::Documents or XML:Twig If you really don't want to work with the Perl data structures, then an alternative is to work with XML::LibXML directly, since you've already got that, and not use XML::Compile at all. For example, here is a tutorial. (Disclaimer: I haven't worked with XML::Compile extensively so some of the above is based on my understanding of the docs.)	[reply]
