用XSL, 这种转换器的实现有很多
下面给出从A->B 和B->A的xsl文件

A2B.xsl

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:template match="/">
    <message>
      <messagetype>
        <xsl:value-of select="head/messagetype"/>
      </messagetype>
      <version>
        <xsl:value-of select="head/version"/>
      </version>
      <xsl:apply-templates select="head/item"/>
    </message>
  </xsl:template>
  <xsl:template match="head/item">
    <record>
      <id>
        <xsl:value-of select="property[name='id']/value"/>
      </id>
      <age>
        <xsl:value-of select="property[name='age']/value"/>
      </age>
      <score>
        <xsl:value-of select="property[name='score']/value"/>
      </score>
    </record>
  </xsl:template>
</xsl:stylesheet>

B2A.xsl

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:template match="/">
    <head>
      <messagetype>
        <xsl:value-of select="message/messagetype"/>
      </messagetype>
      <version>
        <xsl:value-of select="message/version"/>
      </version>
      <xsl:apply-templates select="message/record"/>
    </head>
  </xsl:template>
  <xsl:template match="message/record">
    <item>
      <property>
        <name>id</name>
        <value>
          <xsl:value-of select="id"/>
        </value>
      </property>
      <property>
        <name>age</name>
        <value>
          <xsl:value-of select="age"/>
        </value>
      </property>
      <property>
        <name>score</name>
        <value>
          <xsl:value-of select="score"/>
        </value>
      </property>
    </item>
  </xsl:template>
</xsl:stylesheet>

Jove,thanks very much for your response,

but node like 'id','age','score' in document B should not be hard-coded,they should get from item/property/name.

<xsl:template match="head/item">
  <record>
    <id>id should not be hard-coded here,should get from item/property/name>

      <xsl:value-of select="property[name='id']/value"/>
    </id>
    <age>
      <xsl:value-of select="property[name='age']/value"/>
    </age>
    <score>
      <xsl:value-of select="property[name='score']/value"/>
    </score>
  </record>
</xsl:template>

Posted by: wishmaster Posted on: 2005-03-14 16:26 it should be pretty easy and straightforward to deal with this in webMethods. you need to learn by reading more docs...

Thanks for kind response.

yes , maybe it's so pretty easy to deal with this problem in webMethods after several days' reading or several months' development,and i absolutely believe that there is some way in webMethods.

but you know, for a new comer who faces to resolve this problem urgently want to ask for the straightforward solutions.

and i tried some builtin service like 'recordlistToRecord','recordToRecordlist','appendToRecordList',etc.also i have read the related docs,but i can't get the result i wanted.so i asked the help here.
