in reply to XPath to XML

Hi tosaiju

Could you please give us an example how this should ideally work?

Like showing desired input & output?


IIRC does XPath allows various wildcards on various axis to seek flexibly within the doc tree.

Thats pretty complex or just impossible to use such incomplete information as a document definition.

But if you don't allow wildcards your pretty close at defining how to put data into nested structures (AoH...). (something like Data::Diver comes to mind or just plain autovivification)

So using a module which uses something like XPath to set Perl datastructures and exporting them to XML (e.g. see cpan for dump xml) could be a way to address this task.

    Thanks LanX for the update.

    lets take I have an input like below and related data,

    Any chance of getting an XML file like below,

    <book category="COOKING">
    <title lang="en">Everyday Italian</title>
    <author>Giada De Laurentiis</author>

    I undersatnd Xpath generally works the otherway around and traversing XML file, but wondering any modules - which helps in constructing XML file from given XPath.

    something like as mentioned in below site
    but this is in Java and the usage looks simple

      Well, that usage is much simpler than what you posted but hey, if works use it

      I vaguely recall seeing that before, writing (tree) like that before , and my code practically already does that :P

      update: [cpan://xpath xml ] [cpan://xpath parser ] -> XML::XPathToXML - Generates XML document from XPath expressions

      See, I knew xsh had it :)

        That looks good. Let me play with this now.
        Thanks a lot.
