    Discussion and comments

    High performance text editing and parsing of text files, aligning and indenting XML, print, print preview, e-mail sending, text encoding selection and conversion, Unicode character functions, and C++ code generation to see how to create or navigate your XML with CMarkup.

    free XML editor and RSS

    Foxe supports most encoding names in the XML Declaration encoding or HTML charset, plus UTF-16 BOM and UTF-8 preambles, only assuming the system current locale ANSI charset when it doesn't pass UTF-8 autodetection.

    Programmable XML tool

    Foxe is growing as an XML tool with FOAL scripting for processing documents with CMarkup functions using C++ syntax. It can automatically generate a program for you when you right-click on an element or attribute. In debugging mode you can watch as it extracts information from documents and builds other documents.

    Unicode features of the free XML editor

    The firstobject XML editor also has some unique Unicode text features. If you want to get any character into your document and you don't know how to type it, just type the Unicode code point number and right-click Convert Char Ref e.g. Euro: € € U+20AC U-20AC or 8364. Use the Char Unicode menu option to display the Unicode code point and range of the character to the right of the cursor or any number of selected characters. e.g.

    <?xml version="1.0" encoding="shift_jis"?>

    U+20AC (8364, Currency Symbols 20A0 - 20CF) UTF-8 E2 82 AC shift_jis N/A €
    U+4E2D (20013, CJK Unified Ideographs 4E00 - 9FFF) UTF-8 E4 B8 AD shift_jis 92 86 中
    U+3059 (12377, Hiragana 3040 - 309F) UTF-8 E3 81 99 shift_jis 82 B7 す

    They are not lying when they claim "high performance"; this program wisely avoids the conventional XML DOM approach...

    a nifty, free XML editor. Best part is, it handles Unicode flawlessly, at least as far as I've seen. It even handles UTF-8 both with and without BOMs, which is a fairly common failing I've run across in other text and XML editors.

    There has been many times when I've been overwhelmed by the talent and generosity of the freeware coding community, but you've definitely taken the biscuit!

    I needed to do some copy/paste and editing for a .xml file on my windows mobile phone and found this through the Bing search engine. I love the small footprint and easy to use format.

    Re: Data Warehousing. I came across your editor (searching google for "xml formatter"), and it's exactly what I've been looking for. I have wanted a simple XML editor that:

  • formats ugly XML
  • colors based on syntax
  • lets me edit the text directly
  • lets me traverse the tree
  • prints with syntax coloring
  • is free
  • You would (might) be amazed at how hard it is to find just that.

    your editor helped me to quickly gain an insight of the structure of a large xml document.
