| Hi, no, you can only write to a file by erasing its content first. But you could try to read the content of the file before writing to it ;) Cheers, Emil |

| Hi, by using local file = io.open(filename, "r"); you should be able to open a file for rading its content. What you do with the information in the file afterwards is up to you ;) Cheers, Emil |

| Hi, did that work? If i try to do that, I get always a warning "Warning: io.open, only write mode ('w') is allowed" and the file is not opened. Part of my code: local oldFile; if fileExists(newFileName) and fileExists(oldFileName) then oldFile = io.open(oldFileName, "r"); ..... end; What's wrong with my code? Regards Karl |

| Hi, that's correct io.open only works in the "w" mode. But there's an other way to read the contents of an xml file. e.g. line 14 in: http://ls-mods.de/scriptDocumentation.php?lua_file=handTools/Chainsaw Cheers, Emil |

| Hi, you mean line 24? ??local xmlFile = loadXMLFile("TempXML", xmlFilename); ?? My problem is, that i would like to access "inputbindings.xml" Unfortunately, all the entries have the same secondLevel.id (input or axis). So, i can not access a specific line by the ..XML.. functions. Regards Karl |

| Hi, ups, yes I meant line 24. Well, you could search for the desired line by checking the "name" attribute. (?) Cheers, Emil |

| Hi, i tried the following: ..... xmlFile = loadXMLFile("input_XML", fileName, "gamePadOrder"); ...... local res = getXMLString(id, "inputBinding.input#name"); .... Yes, that works for the first entry. But how do i get all the others? They all start with the same XMLPath... Karl |

| Hi, well, you could have had a look at the scripts in the script documentation to understand how you can access such elements. http://ls-mods.de/scriptDocumentation.php Anyhow ... first element: getXMLString(id, "inputBinding.input(0)#name"); second element: getXMLString(id, "inputBinding.input(1)#name"); third element: getXMLString(id, "inputBinding.input(2)#name"); so on and so forth ... in a loop you could do something like: getXMLString(id, string.format("inputBinding.input(%d)#name", i)); Cheers, Emil |

| Hi, that was the needed information to solve my problem. Thanks a lot, you made my day. Suggestion: - Collect all the scripting information on one page. The info about XML access is on this site and not under "ls-mods.de". - Add the information about ..input(x)#name... to the documentation on this site under the Chapter XMLPath. - Fix the missing or bad links in the documentation on this site. - index to XML - several Links to XMLPath Regards Karl |
