Hi,

I am using flex. But it is about an XML importation so maybe it is the right place to post it (I previously tried on the Flex forum without success).

I want to display some Xml Files. Here I reproduce my code:

* my main file

<?xml version="1.0" encoding="utf-8" ?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx"
               >

   <fx:Script>
    <![CDATA[
         import spark.utils.TextFlowUtil;
         XML.ignoreWhitespace = false;
    ]]>
   </fx:Script>
   <fx:Declarations>
     <fx:XML id="xmlFile" source="testxml.xml"/>
   </fx:Declarations>
   <s:Panel>
     <s:RichEditableText id="code2" editable="false"
            textFlow="{TextFlowUtil.importFromXML(xmlFile)}"/>
   </s:Panel>

</s:Application>

* testxml.xml

<?xml version="1.0" encoding="utf-8"?>
<TextFlow xmlns="http://ns.adobe.com/textLayout/2008"
whiteSpaceCollapse="preserve">
<span>Coucou</span> <
</TextFlow>

If testxml.xml does not contain < (or &rt;), this works fine, but as soon as I put this caracters, whereas the compilation works, the application does not appear in my brownser (I use Linux, I don't have any error message).

Thanks for your help.

Correct answer Jin-Huang

Sorry, but I am continuing with my code . And something really strange is that the code above works fine withe the caracter > !!

How is it possible ?? I really do not understand what happens!

BTW in what way your code can help me? (before I try to understard it)

Thanks

You only need to change the name of the xml file, then with my code, your markup will be imported as textflow even with "<" in the markup.

<?xml version="1.0" encoding="utf-8" ?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx" addedToStage="importer()">
