invalid-characters

I am trying to create a query string of variable assignments separated by the & symbol (ex: "var1=x&var2=y&..." ). I plan to pass this string into an embedded flash file. I am having trouble getting an & symbol to show up in XSLT. If I just type & with no tags around it, there is a problem rendering the XSLT document. If I type & with no tags around it, then the output of the document is & with no change. If I type <xsl:value-of select="&" /> or <xsl:value-of select="&" /> I also get an error. Is this possible? Note: I have also tried &amp; with no success. Kevin Hakanson You can combine

I keep getting a Base64 invalid character error even though I shouldn't. The program takes an XML file and exports it to a document. If the user wants, it will compress the file as well. The compression works fine and returns a Base64 String which is encoded into UTF-8 and written to a file. When its time to reload the document into the program I have to check whether its compressed or not, the code is simply: byte[] gzBuffer = System.Convert.FromBase64String(text); return "1F-8B-08" == BitConverter.ToString(new List<Byte>(gzBuffer).GetRange(4, 3).ToArray()); It checks the beginning of the

I recently have been moving a bunch of MP3s from various locations into a repository. I had been constructing the new file names using the ID3 tags (thanks, TagLib-Sharp!), and I noticed that I was getting a System.NotSupportedException : "The given path's format is not supported." This was generated by either File.Copy() or Directory.CreateDirectory() . It didn't take long to realize that my file names needed to be sanitized. So I did the obvious thing: public static string SanitizePath_(string path, char replaceChar) { string dir = Path.GetDirectoryName(path); foreach (char c in Path

I noticed that in Internet Explorer (but, unfortunately, not in the other browsers I tested), you can use some Unicode variable names. This made my day, and I was absolutely delighted that I could write fun Unicode-laden code like this: var ктоείναι草泥马 = "You dirty horse.", happy☺n☺mat☺p☺eia = ":)Yay!", ಠ_ಠ = "emoticon"; alert(ктоείναι草泥马 + happy☺n☺mat☺p☺eia + ಠ_ಠ); For some reason, though, ◎ܫ◎ , ♨_♨ and ☺ are not valid variable names. Why do ಠ_ಠ and 草泥马 work, but ◎ܫ◎ , ♨_♨ and ☺ don't? EDIT: Test it out in your browser on JSFiddle . I've tested it in Internet Explorer 9, Chrome, Firefox, and
