David – yeah I think the guy that wrote the script was probably sleep deprived when he did it 😊 …. here is the one that meets new requirements as well as a bit more 😊.

 

Since spacing matters in Python, attached one should fully run if saved as a file.

 

# --- Start of script ---

from lxml import etree

import gzip

import sys

 

onlyMultiple = True

 

if len(sys.argv) > 2:

    if "all" in sys.argv[2].lower():

        onlyMultiple = False

  

if len(sys.argv) > 1:

                data_file = sys.argv[1]

else:

    print ("\nProvide one or two positional parameters:")

    print ("   File name as the first argument.")

    print ("   Optional second argument: 'all' to display all tickers, not just those with multiple namespaces.\n")

   exit()

 

namespaces = dict()

 

try: 

                with gzip.open(data_file, "rb") as f:

                                context = etree.iterparse(f, tag='{http://www.gnucash.org/XML/gnc}commodity')

                

                                for event, elem in context:

                                                symbol = elem[1].text

                                                namespace = elem[0].text

                                                elem.clear()

 

                                                if symbol in namespaces: 

                                                                namespaces[symbol] = namespaces[symbol] + ", " +namespace

                                                else:

                                                                namespaces[symbol] = namespace

  

                for ticker in sorted(namespaces.keys()):

                                if onlyMultiple:

                                                if namespaces[ticker].count(",") > 0:

                                                                print ("{}:{}".format(ticker, namespaces[ticker]))

                                else:

                                                print ("{}:{}".format(ticker, namespaces[ticker]))

 

except Exception as e:

                print ("Error: {}".format(e))

# --- End of script ---

Kalpesh, 

It is nice to see how a user could use Python to get at this information, but it seems to me that having to supply a list of symbols to the script defeats the point of trying to find those symbols that have secondary namespaces. 

I wonder whether there is a Python analog for "find all securities that are not currencies" that Wm provided in his SQL...

Script attached in-case spaces gets munged up by the list server which I already show done so.

Here is the Python script that will do so. You'll need to provide full path to your compressed XML data file as the first argument, followed by list of symbols to find namespace(s) for. All parameters separated by one or more spaces.

Example
c:\CloudDrives\OneDrive\QuickenStuff\HELPERS>python display_namespaces.py c:\data\gnucash\example.gnucash NANC NANC:CBOE NANC:CBOE - US

You will need Python 3.X installed, along with lxml and gzip libraries installed in Python for the script to work. You would copy & paste everything between '# ---' delimiters to a file for a fully running script.

Now you have both ways to do it. Hope these helps.


# --- Start of Script
from lxml import etree
import gzip
import sys

if len(sys.argv) > 2:
      tickers = [ticker.strip() for ticker in sys.argv[2:]]
      data_file = sys.argv[1]
else:
    print ("\nProvide two positional parameters:")
    print ("   File name as the first.")
    print ("   Specify one or more tickers as second and onward separated by a space.")
    exit()
    
with gzip.open(data_file, "rb") as f:
      context = etree.iterparse(f, tag='{http://www.gnucash.org/XML/gnc}commodity')
  
      for event, elem in context:

             symbol = elem[1].text
             namespace = elem[0].text
             elem.clear()
    
             if any(symbol.lower() == ticker.lower() for ticker in tickers):
                     print ("{}:{}".format(symbol, namespace)) # --- End of Script

I don't think you can do it in gnc but here is some SQL that does it


  _____  

with m_cnt as (

select mnemonic, count(*) as cnt

from commodities

group by mnemonic

having cnt > 1

)

select namespace, mnemonic

from commodities

where mnemonic in (select mnemonic from m_cnt)

;

 Anyone know of a way to find stocks in more than one Namespace?
