I use excel macro to convert data into xml file already. It is no problem to read xml in IE, the formalt is clear. But the format has problem if open with notepad++. All the words stand in a very long line.Is it the problem of xml heading? i guess.\[code\]<?xml version="1.0" encoding="UTF-8" ?>\[/code\]I try to open with xml notepad 2007, the format is ok. But cannot edit.and it says:"Your XML document contains no xml-stylesheet processing instruction. To provide an XSLT transform, add the following to the top of your file and edit the href attribute accordingly:< ?xml-stylesheet type="text/xsl" href="http://stackoverflow.com/questions/12294554/stylesheet.xsl"? >is it means i need to change the heading? the heading is the problem root?
