This module provides implements the load() method of Treex::PML::Instance and is not intended for direct use.
The module analyses a Treex::PML::Schema and generates Perl code to parse PML instances conforming to that schema (by generating handlers for individual data types). XML::CompactTree::XS (or XML::CompactTree) is used to first slurp the XML into in-memory Perl data structures (much faster than using SAX, XML::LibXML::Reader, DOM, or any other parsing strategy known). The Perl code generated by this module transforms these data structures into the coresponding Treex::PML objects.
The handlers for last 50 PML schemas are cached in memory, to boost processing large collections of PML instances conforming to only a few distinct schemas.
The module also implements automatic pluggable XSLT, external command, or Perl pre-processing (transformation) of the input document; this pre-processing can be specified in a configuration file (
pmlbackend_conf.xml, see "CONFIGURATION" in Treex::PML::Instance for more details).
If the environment variable PML_COMPILE_DUMP=1 is set, the module dumps the generated code to the
.pml_compile.d/folder in the current working directory. This is very for debugging or profiling the generated code.
