我几乎是第一次使用 xslt 和 xpath，所以请多多包涵。我有以下xml（这只是其中的一小部分）：

<scriptflow description="" entrynodeid="301033924" leftbranch="809" name="Annual Charge and Banding v1.0" quickcode="" rightbranch="810" scriptflowid="301001711" status="1" templateid="-1">

  </scriptnode>

  <subprocessnode nodeid="301033931" scriptflowid="101000700" scriptflowname="Anything Else v1.0" xpos="1120" ypos="20" /> 
- <scriptnode eventid="-1" name="Valuation" nodeid="301033932" templateid="1" templatename="action" text="[bookmark=action] If their propery banding is showing another authority, give them their details by click on authority name on right hand screen [/bookmark]" url="" xpos="810" ypos="190">

  <nodelink fromnode="301033933" fromnodeexit="0" tonode="301033930" /> 
  <nodelink fromnode="301033934" fromnodeexit="0" tonode="301033930" /> 
  </scriptflow>

我需要从这个 xml 创建一个流程图。将一个节点链接到另一个节点的内容位于此 xml 的末尾：

      <nodelink fromnode="301033924" fromnodeexit="0" tonode="301033927" /> 
....
      <nodelink fromnode="301033933" fromnodeexit="0" tonode="301033930" /> 
      <nodelink fromnode="301033934" fromnodeexit="0" tonode="301033930" /> 
      </scriptflow>

我到目前为止的xslt如下：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>
    <xsl:output method="html" />

  <xsl:param name="logo"></xsl:param>
  <xsl:param name="folder"></xsl:param>
<xsl:key name="Keytest" match="scriptnode/scriptnodeexit[@exitid]" use="@exitid"/> 

    <xsl:template match="nodelink">
        <xsl:for-each select=".">
        <xsl:choose>
              <xsl:when test="(preceding-sibling::scriptnode/@nodeid)mod @fromnode=0">
            NodeID:<xsl:value-of select="preceding-sibling::scriptnode/@nodeid"/>,
            Name:<xsl:value-of select="preceding-sibling::scriptnode/@name"/>,
              </xsl:when>
              <xsl:otherwise>
                <xsl:text>*no nodeID/name match*</xsl:text>
              </xsl:otherwise>
        </xsl:choose>
    </xsl:for-each>

            <xsl:choose>
              <xsl:when test="(preceding-sibling::scriptnode/scriptnodeexit/@exitid) mod @fromnodeexit=0 and (preceding-sibling::scriptnode/@nodeid) div @fromnode=1 and (preceding-sibling::scriptnode/@nodeid) = @fromnode">
                From Node ExitID: <xsl:value-of select="@fromnodeexit"/>
                From Node ID: <xsl:value-of select="@fromnode"/>,
                ExitID:<xsl:value-of select="preceding-sibling::scriptnode/scriptnodeexit/@exitid"/>,
        Exitname:<xsl:value-of select="preceding-sibling::scriptnode/scriptnodeexit/@exitname"/>
              </xsl:when>
        </xsl:choose>             

        <xsl:choose>
      <xsl:when test="(preceding-sibling::scriptnode/scriptnodeexit/@exitid)mod @fromnodeexit=0">
        ExitID:<xsl:value-of select="preceding-sibling::scriptnode/scriptnodeexit/@exitid"/>,
        Exitname:<xsl:value-of select="preceding-sibling::scriptnode/scriptnodeexit/@exitname"/>
    <img src="{$logo}" />
      </xsl:when>
    <xsl:otherwise>
      <xsl:text>*no editID/exitname match*</xsl:text><img src="{$logo}" />
    </xsl:otherwise>
    </xsl:choose>
          FromNodeExitID:<xsl:apply-templates select="@fromnodeexit"/>, 
          From Node: <xsl:apply-templates select="@fromnode"/>, 
          To Node: <xsl:apply-templates select="@tonode"/>
        <img src="{$logo}" /><br />
  </xsl:template>
</xsl:stylesheet>

我正在尝试创建一个树结构以供以后格式化以使其成为流程图，但我正在努力循环遍历 scriptnode/scptnode 退出属性。我无法上传所需流程图的图像，但我的 xslt 是在正确的轨道上还是完全关闭？

这会使用 nodelink 从您的数据中构建一棵树：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="html" />

    <xsl:param name="logo"/>
    <xsl:param name="folder"/>

    <xsl:key name="nodes" match="*[@nodeid]" use="@nodeid"/>
    <xsl:key name="links" match="nodelink" use="@fromnode"/>

    <xsl:template match="/scriptflow">
        <h1>Entry point</h1>
        <ul>
            <xsl:apply-templates select="key('nodes', @entrynodeid)"/>
        </ul>
    </xsl:template>

    <xsl:template match="*[@nodeid]">
        <li>
            <h2><xsl:value-of select="local-name()"/>: <xsl:value-of select="@name"/></h2>
            <xsl:apply-templates select="scriptnodeexit"/>
        </li>
    </xsl:template>

    <xsl:template match="scriptnodeexit">
        <h3>Link: <xsl:value-of select="@exitname"/></h3>
        <ul>
            <xsl:apply-templates select="key('nodes', key('links', current()/../@nodeid)[@fromnodeexit=current()/@exitid]/@tonode)"/>
        </ul>
    </xsl:template>

</xsl:stylesheet>
