Hi AJ! Sorry about that, i will revert to the users list. The problem with the script is that it does not execute the os.system() commands at all, not that it generates the file at the wrong place or anything. Do you know why this happens and how i can remedy it? I seem to have found an old thread of someone facing the same problem but the suggestion solution is not appropriate for my case. I have even made sure that the CLASSPATHS have been set to the directory holding my .jar file http://mail.zope.org/pipermail/zope-dev/2003-June/019918.html Thanks again! wan Here is my code : def removeIllegalChars( tgtString ): import os import sys from yahoo.search.news import NewsSearch import re tgtString = re.sub('<([^!>]([^>]|\n)*)>', '', tgtString) tgtString = re.sub('<([^>]([^>]|\n)*)>', '', tgtString) tgtString = re.sub('\n', '', tgtString) tgtString = re.sub('\t', '', tgtString) tgtString = re.sub('\r', '', tgtString) tgtString = re.sub(' ', '', tgtString) if tgtString: try: tgtString = str(tgtString) except UnicodeEncodeError: tgtString = str(tgtString.encode('U8')) return tgtString def getYahooAPI(): import os import sys from yahoo.search.news import NewsSearch import re queryWord = "Singapore" print ("Fetching data from YahooAPI with query : " + queryWord ) srch = NewsSearch('YahooDemo',query = "Singapore asean cup", language = 'en', results = 50) info = srch.parse_results() info.total_results_available homedir = os.getcwd() tgtFile = homedir + "/Extensions/InputString.txt" writeFile = open(tgtFile, 'w') for result in info.results: writeFile.write("<Article>\n") writeFile.write("<Title>\n") writeFile.write(removeIllegalChars(result['Title'])+ "\n") writeFile.write("<URL>\n") writeFile.write(removeIllegalChars(result['ClickUrl']) + "\n") writeFile.write("<Summary>\n") writeFile.write(removeIllegalChars(result['Summary']) + "\n") writeFile.write("<Date>\n") writeFile.write(removeIllegalChars(result['PublishDate']) + "\n") writeFile.write("<Source>\n") writeFile.write(removeIllegalChars(result['NewsSource']) + "\n") writeFile.write("<Body>\n") writeFile.write(removeIllegalChars(result['Summary']) + "\n") writeFile.write("<EndOfFile>") writeFile.close def runYahooSearch2(self): import os import sys from yahoo.search.news import NewsSearch import re #----------------------------------------------------------------------------------------------------------- # still trying to figure out how to get the absolute path to this script # commands below work for windows... but not for linux.
