Ant:build.xml; XML document structure must start and end within the same entity

Question

I have the following directory structure

+project
    +--profile
         +---src
         +---WebContent
         +---build

I am trying to compile and copy using Ant, but when I execute the following file I get this error and nothing else. 文件时，我得到此错误而不是其他任何内容。 I checked a couple of almost similar questions but none of them helped, the only question similar to this was collected by adding any thing within like a comment which didn't work for me. What am I missing in the build file?

<?xml version="1.0"?>
<project name="profile" basedir="." default="Task-of-build">
<property name="src.dir" value="src"/>
<property name="webcontent.dir" value="WebContent"/>
<property name="javadoc" value="doc"/>
<property name="name" value="profile"/>
<property name="build.dir" value="${webcontent.dir}/WEB-INF/classes"/>
<property name="backup.dir" value="C:/project/backup"/>

I believe this is the problem:

<doctitle><![CDATA[<h1>=Profile Mgnt =</h1>]]</doctitle>
<bottom><![CDATA[Copyright 2011. All Rights reserved></bottom>

Neither of your CDATA sections are properly terminated, so your file is simply not valid XML. I think you should have:

<doctitle><![CDATA[<h1>=Profile Mgnt =</h1>]]></doctitle>
<bottom><![CDATA[Copyright 2011. All Rights reserved>]]></bottom>

... although as the second of these strings does anything which requires escaping in XML, I woudln't even use a CDATA section for it:

<doctitle><![CDATA[<h1>=Profile Mgnt =</h1>]]></doctitle>
<bottom>Copyright 2011. All Rights reserved></bottom>

... and even the first one just needs the open angle brackets escaping:

<doctitle>&lt;h1>=Profile Mgnt =&lt;/h1></doctitle>
<bottom>Copyright 2011. All Rights reserved></bottom>

(You might chose to convert > to > as well, but I don't believe you have to.)
