DESCRIPTION

OpenXML::Properties helps to check, set and remove custom properties in a MS Office Word, Excel and Powerpoint documents in OpenXML format, i.e., 2007 and higher.

Custom properties in documents of older versions of MS Office could be accessed/modified using the module Win32::OLE, but there are no such modules for OpenXML documents.

OpenXML documents are nothing but a group of xml files combined in a zip format.

Please check http://msdn.microsoft.com/en-us/office/bb265236.aspx for further info on OpenXML

This module uses Archive::Zip to read the Office files (.docx, .xlsx and .pptx) and XML::Xpath to read/write the xml files.

Code is written using Moose.

NOTE

This module changes only the custom properties in the document but does not change the data. However, since this is still in a development phase, please take a backup of your documents before using this module.

Constructor

    The constructor to OpenXML::Properties requires the FileName argument. The FileName is the file to which you wish to view/add/remove custom properties.

    my $doc = OpenXML::Properties->new(FileName => 'C:\temp\test.xlsx');

    The constructor also takes an optional 'verbose' parameter.

    my $doc = OpenXML::Properties->new(FileName => 'C:\temp\test.xlsx', verbose => 1);

    'verbose' will write debugging information to 'C:\temp\openxml_properties_log_$$.txt' where $$ is the pid of the process.

Methods

add_custom_property($custom_property_name, $custom_property_value)

add_custom_property requires 2 parameters to be passed, the property name and value to be applied to the document. It returns error as a string, if any. If nothing is returned, then the property was added successfully.

$doc->add_custom_property($custom_property_name, $custom_property_value);
remove_custom_property($custom_property_name)

remove_custom_property requires 1 parameter, i.e., the property name to be removed from the document. It returns error as a string, if any. If nothing is returned, then the property was removed successfully.

$doc->remove_custom_property($custom_property_name);
has_custom_property($custom_property_name)

has_custom_property checks if the custom property exists. Returns true if exists, false if it does not.

	if ($doc->has_custom_property($custom_property_name))
    {
        print "Document has $custom_property_name\n";
    }
has_custom_properties($custom_property_name)

has_custom_properties returns the number of custom properties currently applies to the document.

$count = $doc->has_custom_properties
custom_properties

custom_properties returns all custom property names and values in the document, as a hash.

my %props = $doc->custom_properties;
custom_properties_names

custom_properties_names returns all custom properties in the document, as an array.

my @props = $doc->custom_properties_names;
