中文XML论坛--用xsl生成XML树格式

贴子主题：用xsl生成XML树格式

本主题类别:

各位前辈，刚学XML碰到如下问题，想了好久不知道错在哪，请大家指教，谢谢帮助。

任务：将一个xml文件从无层次格式（源文件格式）转到有层次格式（目标文件格式）
测试数据：
源XML文件
<?xml version="1.0" encoding="gb2312"?>
<?xml-stylesheet type="text/xsl" href="test.xsl" ?>
<tree_tests>
<tree_test ID="1" PARENT_ID="0" NAME="ROOT " SIZE="0 " CHILDFLAG="T"/>
<tree_test ID="2" PARENT_ID="1" NAME="A " SIZE="13 " CHILDFLAG="T"/>
<tree_test ID="3" PARENT_ID="1" NAME="B " SIZE="23 " CHILDFLAG="T"/>
<tree_test ID="4" PARENT_ID="1" NAME="C " SIZE="1 " CHILDFLAG="T"/>
<tree_test ID="5" PARENT_ID="2" NAME="A.A1 " SIZE="34 " CHILDFLAG="T"/>
<tree_test ID="6" PARENT_ID="2" NAME="A.A2 " SIZE="6 " CHILDFLAG="F"/>
<tree_test ID="7" PARENT_ID="5" NAME="A.A1.1 " SIZE="7 " CHILDFLAG="T"/>
<tree_test ID="8" PARENT_ID="5" NAME="A.A1.2 " SIZE="5 " CHILDFLAG="T"/>
<tree_test ID="9" PARENT_ID="2" NAME="A.A3 " SIZE="3 " CHILDFLAG="F"/>
<tree_test ID="10" PARENT_ID="3" NAME="B.B1 " SIZE="5 " CHILDFLAG="T"/>
<tree_test ID="11" PARENT_ID="4" NAME="C.C1 " SIZE="6 " CHILDFLAG="F"/>
<tree_test ID="12" PARENT_ID="10" NAME="B.B1.1 " SIZE="6 " CHILDFLAG="F"/>
<tree_test ID="13" PARENT_ID="7" NAME="A.A1.1.a " SIZE="12 " CHILDFLAG="F"/>
</tree_tests>
目标XML文件希望如下：
<tree_test ID="1" NAME="ROOT" >
 <tree_test ID="2" NAME="A" >
 <tree_test ID="5" NAME="A.A1 ">
 <tree_test ID="7" NAME="A.A1.1 >
 <tree_test ID="13" NAME="A.A1.1.a ">
 <tree_test ID="8" NAME="A.A1.2 >
 <tree_test ID="6" NAME="A.A2 ">
 <tree_test ID="3" NAME="B" >
 <tree_test ID="10" NAME="B.B1" >
 <tree_test ID="12" NAME="B.B1.1" >
 <tree_test ID="4" NAME="C" >
 <tree_test ID="11" NAME="C.C1">
</tree_test>

我的XLS
<?xml version="1.0" encoding="gb2312" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
 <xsl:template match="/">
 <xsl:call-template name="treetemplate">
 <xsl:with-param name="parent_id" select="0"/>
 </xsl:call-template>
 </xsl:template>

<xsl:template name="treetemplate">
 <xsl:param name="parent_id"/>
 <xsl:for-each select="/tree_tests/tree_test[@PARENT_ID=$parent_id]">
 <xsl:value-of select="." /> 
 
 <xsl:value-of select="$parent_id"/>
 
 Id: <xsl:value-of select="./@ID"/>
 
 PARENT_ID:<xsl:value-of select="./@PARENT_ID"/> 
 NAME: <xsl:value-of select="./@NAME"/> 
 SIZE: <xsl:value-of select="./@SIZE"/> 
 CHILDFLAG:<xsl:value-of select="./@CHILDFLAG"/>
 
 </xsl:for-each>
 <xsl:if test="CHILDFLAG='T'">
 <xsl:call-template name="treetemplate">
 <xsl:with-param name="parent_id" select="./@ID"/>
 </xsl:call-template>
 </xsl:if>
 </xsl:template>
</xsl:stylesheet>

递归有问题，但我想不出问题在哪
