我需要循環使用XSLT代碼？

Question

我很難循環這個。

XML代碼：

<ProcessData> 
    <Messages> 
     <MessageIds/> 
     <MessageNames> 
      <MessageName>tpname1_abc.txt</MessageName>     
      <MessageName>tpname2_def.txt</MessageName> 
      <MessageName>tpname3_pqr.txt</MessageName> 
      <MessageName>tpname4_xyz.txt</MessageName> 
     </MessageNames> 
    </Messages> 
</ProcessData> 

XSLT代碼：

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:output method="text"/> 
    <xsl:template match="/"> 
    Invalid File Received for Enrollments Inbound process in mailbox /sftptps/enrollments/deadletter 


       <xsl:for-each select="/ProcessData/Messages/MessageNames/MessageName"> 
         Username: <xsl:value-of select="substring-before(/ProcessData/Messages/MessageNames/MessageName/text(),'_')"/>  File Name:<xsl:value-of select="substring-after(/ProcessData/Messages/MessageNames/MessageName/text(),'_')"/> 

         <xsl:text>&#xd;</xsl:text> 
     </xsl:for-each> 
    </xsl:template> 
</xsl:stylesheet> 

這是到目前爲止我的輸出：

Invalid File Received for Enrollments Inbound process in mailbox /sftptps/enrollments/deadletter 



         Username: tpname1  File Name:abc.txt 
         Username: tpname1  File Name:abc.txt 
         Username: tpname1  File Name:abc.txt 
         Username: tpname1  File Name:abc.txt 

我需要它是這樣的：

Invalid File Received for Enrollments Inbound process in mailbox /sftptps/enrollments/deadletter 



         Username: tpname1  File Name:abc.txt 
         Username: tpname2  File Name:def.txt 
         Username: tpname3  File Name:pqr.txt 
         Username: tpname4  File Name:xyz.txt 

我在這裏做錯了什麼？我敢肯定，我錯過了一些東西來循環它。

你已經在那裏 - 不要從頂部開始。變化：

<xsl:value-of select="substring-before(/ProcessData/Messages/MessageNames/MessageName/text(),'_')"/> 

到：

<xsl:value-of select="substring-before(.,'_')"/> 

和：

<xsl:value-of select="substring-after(/ProcessData/Messages/MessageNames/MessageName/text(),'_')"/> 

到：

<xsl:value-of select="substring-after(.,'_')"/>

你有什麼現在選擇全部MessageName節點從文檔的根節點開始，並在XSLT 1.0中返回第一個節點的值。
