Add array items in XMP metadata of EPS| Python

To add array items to the XMP metadata of an EPS file, you need to follow these steps:

1. Initialize an input stream for input EPS file.
2. Create an instance of PsDocument from the previously created input stream.
3. Obtain an instance of XmpMetadata from the PsDocument. If the EPS file does not contain XMP metadata, a new one will be created and populated with values from PS metadata comments, then returned to you.
4. You can now add items to the array metadata fields.
5. Initialize an output stream for the output EPS file.
6. Save the EPS file with the updated XMP metadata.

Here is a code snippet demonstrating how to add array items to the XMP metadata in an EPS file in Python:

# The path to the documents directory.
data_dir = Util.get_data_dir_working_with_xmp_metadata_in_eps()
# Initialize the EPS file input stream
ps_stream = open(data_dir + "add_simple_props_input.eps", "rb",)
# Create the PsDocument instance from the stream
document = PsDocument(ps_stream)

try:
    # Get XMP metadata. If EPS file doesn't contain any XMP metadata we get new one filled with values from PS metadata comments (%%Creator, %%CreateDate, %%Title etc)
    xmp = document.get_xmp_metadata()
    
    #Change XMP metadata values
    
    # Add another title. It will be added at the end of array by default.
    xmp.add_array_item("dc:title", XmpValue("NewTitle"))
    
    # Add one more creator. It will be added in the array by an index (0).
    xmp.add_array_item("dc:creator", 0, XmpValue("NewCreator"))
    
    # Save the EPS file with changed XMP metadata
    
    # Create an ouput stream
    with open(data_dir + "add_array_items_output.eps", "wb") as out_ps_stream:
        # Save the EPS file
        document.save(out_ps_stream)
    
finally:
    ps_stream.close()
