我第一次使用xslt和xpath所以请耐心等待。 我有以下xml（这只是它的一小部分）：
<scriptflow description="" entrynodeid="301033924" leftbranch="809" name="Annual Charge and Banding v1.0" quickcode="" rightbranch="810" scriptflowid="301001711" status="1" templateid="-1">

<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事情就在这个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">

</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 ID: <xsl:value-of select="@fromnode"/>,

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形结构，以便以后格式化，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是我的xslt在正确的轨道上还是完全关闭？
答案 0 :(得分：0)
使用nodelink：
从您的数据构建树<?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>
