如何计算类别中的元素并将其与XSLT中的其他类别进行比较 [英] How to count elements in categorys and compare it with other categorys in XSLT

问题描述

我有问题:-)

我想打印出一个xml并为其编写一个xslt.问题是我想用我的xml元素建立一个表，但是我必须计算每行是否具有相同数量的列，如果没有，我必须添加一个value元素.

i would like to print out a xml and write a xslt for it. the problem is that i would like to build a table with my xml-elements but i must count if each row has the same amount of columns and if not i have to add a value element.

我知道一旦设置了值就无法更改变量值，但是我该如何比较进程的类别/表行数量呢? (并添加空行)

i know that i cant change a variables value once i have set the value but how can i compare the categorys/table-rows amount of processes then? (and add empty rows)

XML:

<Settings>
   ...
   ..
  <DashBoard>
    <Category NAME="ph" PICNAME="prh">
      <Process NAME="pd" URL="" PICNAME="prh_prd" />
      <Process NAME="md" URL="" PICNAME="prh_prd" />
      <Process NAME="t" URL="" PICNAME="prh_prd" />
    </Category>
    <Category NAME="cm" PICNAME="cam">
      <Process NAME="ps" URL="" PICNAME="cam_pls" />
      <Process NAME="ea" URL="" PICNAME="cam_eas" />
    </Category>
    <Category NAME="sm" PICNAME="sum">
      <Process NAME="frm" URL="" PICNAME="sum_frm" />
    </Category>
  </DashBoard>
</Settings>

XSLT:

<xsl:stylesheet version="1.0" xmlns:xsl=".....">
  <xsl:output method="xml" indent="yes"/>
  <xsl:variable name="relurl" select="/Settings/Picture/@RELATIVEURL"/>

  <xsl:template match="Settings">
    <table id="dashframe" >
      <xsl:apply-templates/>
    </table>
  </xsl:template>

  <xsl:template match="Category">
    <xsl:variable name="altname" select="@NAME" />
    <xsl:variable name="picname" select="@PICNAME" />
    <tr>
      <th>
        <img alt="{$altname}" src="{$relurl}dash_{$picname}_p_01.png" />
      </th>
      <xsl:apply-templates/>
    </tr>
  </xsl:template>

  <xsl:template match="Process">
    <xsl:variable name="altname" select="@NAME" />
    <xsl:variable name="picname" select="@PICNAME" />
    <td>
      <img alt="{$altname}" src="{$relurl}dash_{$picname}_p_01.png" />
    </td>
  </xsl:template>
</xsl:stylesheet>

所需的输出:

<table id="dashframe" >
    <tr>
        <th>titel 1</th>
        <td>....</td>
        <td>....</td>
        <td>....</td>
    </tr>
    <tr>
        <th>titel 2</th>
        <td>....</td>
        <td>....</td>
        <td></td>
    </tr>
    <tr>
        <th>titel 3</th>
        <td>....</td>
        <td></td>
        <td></td>
    </tr>
</table>

推荐答案

此样式表保存您的样式:

Preserving yours, this stylesheet:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="html"/>
    <xsl:variable name="relurl" select="/Settings/Picture/@RELATIVEURL"/>
    <xsl:variable name="vColumns">
        <xsl:for-each select="/Settings/DashBoard/Category">
            <xsl:sort select="count(Process)" order="descending"/>
            <xsl:if test="position()=1">
                <xsl:value-of select="count(Process)"/>
            </xsl:if>
        </xsl:for-each>
    </xsl:variable>
    <xsl:template match="DashBoard">
        <table id="dashframe" border="1">
            <xsl:apply-templates/>
        </table>
    </xsl:template>
    <xsl:template match="Category">
        <tr>
            <th>
                <img alt="{@NAME}" src="{$relurl}dash_{@PICNAME}_p_01.png"/>
            </th>
            <xsl:call-template name="process"/>
        </tr>
    </xsl:template>
    <xsl:template name="process">
        <xsl:param name="pColumn" select="number($vColumns)"/>
        <xsl:if test="$pColumn">
            <xsl:call-template name="process">
                <xsl:with-param name="pColumn" select="$pColumn - 1"/>
            </xsl:call-template>
            <td>
                <xsl:variable name="vColumn" select="Process[$pColumn]"/>
                <xsl:if test="$vColumn">
                    <img alt="{$vColumn/@NAME}"
                         src="{$relurl}dash_{$vColumn/@PICNAME}_p_01.png"/>
                </xsl:if>
            </td>
        </xsl:if>
    </xsl:template>
</xsl:stylesheet>

使用此输入:

<Settings>
    <DashBoard>
        <Category NAME="ph" PICNAME="prh">
            <Process NAME="pd" URL="" PICNAME="prh_prd" />
            <Process NAME="md" URL="" PICNAME="prh_prd" />
            <Process NAME="t" URL="" PICNAME="prh_prd" />
        </Category>
        <Category NAME="cm" PICNAME="cam">
            <Process NAME="ps" URL="" PICNAME="cam_pls" />
            <Process NAME="ea" URL="" PICNAME="cam_eas" />
        </Category>
        <Category NAME="sm" PICNAME="sum">
            <Process NAME="frm" URL="" PICNAME="sum_frm" />
        </Category>
    </DashBoard>
</Settings>

输出:

<table id="dashframe" border="1">
    <tr>
        <th><img alt="ph" src="dash_prh_p_01.png"></th>
        <td><img alt="pd" src="dash_prh_prd_p_01.png"></td>
        <td><img alt="md" src="dash_prh_prd_p_01.png"></td>
        <td><img alt="t" src="dash_prh_prd_p_01.png"></td>
    </tr>
    <tr>
        <th><img alt="cm" src="dash_cam_p_01.png"></th>
        <td><img alt="ps" src="dash_cam_pls_p_01.png"></td>
        <td><img alt="ea" src="dash_cam_eas_p_01.png"></td>
        <td></td>
    </tr>
    <tr>
        <th><img alt="sm" src="dash_sum_p_01.png"></th>
        <td><img alt="frm" src="dash_sum_frm_p_01.png"></td>
        <td></td>
        <td></td>
    </tr>
</table>
