Free large xml file editor

Most editors work by loading the whole document into memory. This is not possible if the document is to big to load into memory. The Large File Editor overcomes this by only reading the section being displayed, so it's fast, lightweight and able to run on a low specification PC. There is also a Binary mode, making it possible to edit, add and delete binary data an extremely valuable feature as most binary editors do not allow insertion or deletion.

Increasing file sizes means the ability to view and edit these files is becoming more vital in every day life. Typical applications include. Yes, the cut and paste operations only store details of where the block has come from, so you can do a select all on a GB's of data then cut and paste it multiple times and the memory footprint will barely change. That's fine. The editor opens these instantly and can even re-format them.

When a long line is encountered it is wrapped, this length can be configured in the settings. Yes, anything that causes the editor to scan the entire file will be slow the bigger the file the slower. Goto Line needs to count lines from the start of the file, so depending on the line number this can be slow. Just came back to this question as the requirement came up again and saw your response.

This tool seems to be exactlty what I was originall looking for! I haven't yet tried it on huge docs, but 5Mb docs certainly open in a fraction of a second, and pretty-pretting in about a second by just hitting the F8 key. From what you say the performance should scale well into the tens of Mbs. May have some GB docs to try it with later.

That will sort the men from the boys ;- — philsquared. I've just tried it with a MB document and it works like a charm! Tried it on a MB file.

It opens in seconds and shows the element tree. I can click on it to highlight the element in the text pane. Still, this is much better than most programs did on that file and I haven't yet found a better free alternative. Clemens - Great tip. I have just opened a 1.

From trying a few times not rigourous profiling , it seems slightly faster than EditPlus both it's own startup time, and the load time for the 30MB doc - but still parses the whole doc before showing. Hey, Mac OS X? It crashed while loading a 1. Sometimes speed is the only thing that matters, and in such cases Total Commander's Lister is indeed the best. I have used it to quickly find something in files over MB.

Some goes for the FAR Manager's built-in viewer. Thanks Ikurts. I gave it a try and it certainly does a better job than the browers. However, it does appear to be parsing the whole doc before showing it, which is not what I wanted. Voting you up anyway — philsquared. For MacOS, use Xmplify. If your file is one long line, just push the Format button and save the file. EditPad Pro is a superb product. I have opened text files several gigabytes in size with it.

It displays the content instantly, because EditPad Pro uses pointers to access the file directly, and does not do the lazy thing -- which most editors seem to do -- which is to read the entire file into memory at once.

The only problem with EditPad Pro is that it's Windows only, and these days I don't use Windows for anything except video games. EditPad Lite free works stunningly fast.

Very glad to have found that one, after trying non-working other suggestions on Win7 64bit. Download it on editpadlite. On Windows, try Cygwin.

The work which required me to peer into huge files is complete, however I shall investigate this for future use!

I just know its there. Eric Eric 31 1 1 bronze badge. There was an accurate progress bar during that time so I knew how it was getting on. Once open, simple searching, and browsing through the file all worked as well as a small notepad file. It's free. Others I tried This seems to be the best solution for me out of all the other recommendations in the answers.

Thanks a bunch for the recommendation. Not free though after 30 days. I like it well enough to just purchase it though. JeffOrris - just clarifying which editor your commenting on PilotEdit Lite is free forever as far as I can see.

Are you talking about EmEditor Pro Trial? It is PilotEditLite. I took a look again at the download That's strange - mine doesn't say that at all. Obviously I have been pressing "try it" Clint Ecker Clint Ecker 1, 1 1 gold badge 10 10 silver badges 12 12 bronze badges. Will keep those for future reference. At the time I needed to edit a bad record deep inside a tremendous file.

When I'm faced with an enormous log file, I don't try to look at the whole thing, I use Free File Splitter Admittedly this is a workaround rather than a solution, and there are times when you would need the whole file. Martin Martin 2, 14 14 silver badges 14 14 bronze badges. Martin, This is definitely a workaround instead of a solution. The program itself should split the file when we are viewing it but it should not be a detail that the user us had to bother with.

HxD -- it's a hexeditor, but it allows in place edits, and doesn't barf on large files. But it has a fixed column width. How can we make it recognize lines? Rich Rich 14k 2 2 gold badges 61 61 silver badges bronze badges.

As their site claims : EmEditor is now able to open even larger than GB or 2. Not free though.. Alex Klunniy Alex Klunniy 1 1 silver badge 8 8 bronze badges. Todua T. Todua I guess my hardware is restricting me then? It just wont open it. Textpad support forum also confirms it. PhiLho PhiLho I will check that out. Anything written in ASM is worthy of a look! It can typically load files in excess of 10 megabytes with no problems.

It still loads the whole thing into memory, so this is no good for editing a multi GB text file. Rich TheGun is an old project even 4 years ago, when I mentioned it , 10 MB was lot of memory at the time It is probably a 32bit project, so it is likely to have a hard limit around 2 GB anyway. Which was science-fiction when it was designed! PhiLho, while I agree with all your points, none of them addresses the fact that this is a poor answer to the question asked. The rest of your answer refers vaguely to various programming techniques, but does not offer a solution.

Indeed and so are most of the answers to this thread! Hence my question about the available memory. At the time, I hadn't a computer with more than 4 GB of memory, so I couldn't test to be sure
