But if even one zipped file was big the same would apply.Alan G.Message: 2 Date: Wed, 11 Mar 2009 12:26:16 +1100 From: Lie RyanSubject: Re: [Tutor] memory error files over 100MB To: tutor at python.org MessageID:ContentType: text/plain; charset=UTF8; format=flowedSander Sweers wrote: > 2009/3/10 Alan Gauld : >>> newFile.w

Solid archive (multiple filescompressed as a single big file) may need to be fully extracted, exceptif the algorithm can somehow figure out a way of extracting a singlefile from a solid archive without extracting everything first.Message: 3 Date: Tue, 10 Mar 2009 21:44:30 0400 From: Emad Nawfal (???? ????)Subject: [Tutor] How can I extract a specific sublist from a nested list?

 ment.I am stuck, however, at one element.I want to extract several differenct elements per line, creating a comma separated variable (CSV) line that can be imported to a spreadsheet.Not all elements are in each line or part of the XML document  so if an element is not in a line, I would leave a blank (2 commas).I can probably figure that out  it's the extracting multiple elements and putting them in one line that has me stumped.Help would be greatly appreciated.Thank you.What I have so far (and I would like to stick to the DOM model):import xml.dom.minidom import sys datasource=open(sys.argv[1]) domDatasource=xml.dom.minidom.parse(datasource)def getText(nodelist): rc="" for node in nodelist: if node.nodeType == node.TEXTNODE: rc=rc+node.data return rcdef HandleStatus(Finding): for Status in Finding: print getText(Status.childNodes)HandleStatus (domDatasource.getElementsByTagName("FINDINGSTATUS"))domDatasource.unlink()An excerpt of the xml file:GD2.0.8.8TRUEDTBI134Allow paste
