Requesting for your kind help...(want to preserve Leading & trailing spaces)

Question

Hello Team,<br /><br />Can you please help in the following issue:<br />I am trying to preserve white space(leading and trailing  L&T) as is on the User Interface.  We have built our UI using Flex 3.0 SDK. <br /><br />From Java side, I am able to carry the value with L&T spaces till the call goes to Flex .mxml and here response object assigning as  <br /><br /> var metaConfig:XML = event.result as XML;<br />But here L&T spaces are not visible along with value of ID.<br />I used to see it by using Alert.show(event.result.toString());<br /> <br />Flex Output is as:<br /><br />       <allScalarMetadataFields><br />      <id>TEST</id><br />      <name>test name</name> <br />.<br /><br />But from java[in Servlet/in service] side I can see the output as:<br /><br />   <allScalarMetadataFields><br />       <id>   TEST  </id><br />       <name>   test name    </name><br />.<br /><br />Java(Servlet) code is as follows:<br />      OutputStream writer = response.getOutputStream();<br />      OutputStreamWriter outputStreamWriter = new OutputStreamWriter(writer,"UTF-8");<br />JAXBContext context = JAXBContext.newInstance(object.getClass(), object.getClass());<br />         Marshaller m = context.createMarshaller();<br />         m.marshal(object, writer);<br />.Here marshal follow a standard structure for XML to map  it into writer same as what Flex XML follows.....<br /><br />Note, there is no any other issue/fault  with Flex and java except this white spaces.<br /> <br />Flex .mxml code is as:<br /><br />protected var _fieldXml:XML;<br />      public function MetadataFieldWrapper(xml:XML = null)<br />            {<br />                  if (xml == null)<br />                  {<br />       xml = <allScalarMetadataFields xml:space="preserve"><br />               <id /><br />                <name /><br /><br />...<br /><br /> Servlet is getting called as :<br /><br />            _webService = new HTTPService();<br />                  _webService.url = serviceUrl;<br />                  _webService.method = "POST";<br />                  _webService.resultFormat = "e4x";<br />                  _webService.contentType = "application/xml";<br /><br />.<br />_webService.headers = { "serviceName":serviceName, "serviceMethod":serviceMethod };<br />                  _webService.send(param);<br /><br />I want to preserve the L&T spaces along with ID/name .<br />Please help me how to allow these L& T spaces in Flex XML object?<br /><br /> <br />Thanks in Advance.<br />Regards,<br />Venu.

In the future this type of question should be asked on flexcoders as<br />it doesn't relate to the development of the Flex SDK.<br /><br />To preserve whitespace look at the documentation for XML.ignoreWhitespace.<br /><br />-- Daniel R. <[email protected]> [http://danielr.neophi.com/]<br /><br />On Wed, Nov 12, 2008 at 8:19 AM, venubwal <[email protected]> wrote:<br />> A new discussion was started by venubwal in<br />><br />> Developers --<br />>   Requesting for your kind help...(want to preserve Leading & trailing<br />> spaces)<br />><br />> Hello Team,<br />><br />> Can you please help in the following issue:<br />> I am trying to preserve white space(leading and trailing  L&T) as is on the<br />> User Interface.
