Question

我有一个从TEI XML文档生成的站点，其中一个元素是顶部的一组缩略图，取自文件中存在的jpgs数。包含这些jpgs的XML如下：

<sourceDoc xml:id="TextContent">
    <surfaceGrp xml:id="wall" n="South Wall">
        <surface xml:id="p.1" n="panel">
            <label>Verse 27</label>
            <graphic url="sw_test_1.jpg"/>
        </surface>
        <surface xml:id="EETS.T.30">
            <label>Verse 30</label>
            <graphic url="sw_test_2.jpg"/>
        </surface>
        <surface xml:id="EETS.T.27">
            <label>Verse 27</label>
            <graphic url="sw_test_3.jpg"/>
        </surface>
        <surface xml:id="EETS.T.56">
            <label>Verse 56</label>
            <graphic url="sw_test_4.jpg"/>
        </surface>
        <surface xml:id="EETS.T.57">
            <label>Verse 57</label>
            <graphic url="sw_test_5.jpg"/>
        </surface>
        <surface xml:id="EETS.T.58">
            <label>Verse 58</label>
            <graphic url="sw_test_6.jpg"/>
        </surface>
        <surface xml:id="EETS.T.59">
            <label>Verse 59</label>
            <graphic url="sw_test_7.jpg"/>
        </surface>
    </surfaceGrp>
</sourceDoc>

我正在将以下相当混乱的XSL应用于它，它与上面存在的代码配合使用并利用tei命名空间：

    <xsl:template name="menuWidth">
        <xsl:choose>
            <xsl:when test="//tei:sourceDesc[1]/@xml:id='Clopton_Chantry_Chapel'">

            <xsl:otherwise>
                <xsl:attribute name="id">page</xsl:attribute>
            </xsl:otherwise>

            <div id="centerMenu">

这个代码适用于单个surfaceGrp语句，如第一张图所示，但是当我必须将surfaceGrp包装在另一个surfaceGrp中时，它只适用于最里面的surfaceGrp { {1}}。我的想法是，如果我通过../变量中的group_position再上升一级，它将显示所有项目，但这似乎不起作用，如第二张图所示。

理想情况下，我希望XSL生成的HTML看起来像这样，每个项目的缩略图显示：

<div id="centerMenu">
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_1.jpg">
        <img class="thumbnail" src="../../Quis_Dabit/Clopton/Thumbnails/sw_test_1-thumbnail.jpg" alt="First Panel" />
    </a>
</span>
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_2.html">
        <img class="thumbnail" src="../../Quis_Dabit/Clopton/Thumbnails/sw_test_2-thumbnail.jpg" alt="Second Panel" />
    </a>
</span>
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_3.html">
        <img class="thumbnail" src="../../Quis_Dabit/Clopton/Thumbnails/sw_test_3-thumbnail.jpg" alt="Third Panel" />
    </a>
</span>
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_4.html">
        <img class="thumbnail" src="../../Quis_Dabit/Clopton/Thumbnails/sw_test_4-thumbnail.jpg" alt="Fourth Panel" />
    </a>
</span>
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_5.html">
        <img class="thumbnail" src="../../Quis_Dabit/Clopton/Thumbnails/sw_test_5-thumbnail.jpg" alt="Fifth Panel" />
    </a>
</span>
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_6.html">
        <img class="thumbnail" src="../../Quis_Dabit/Clopton/Thumbnails/sw_test_6-thumbnail.jpg" alt="Sixth Panel" />
    </a>
</span>
</div>
<div id="rightMenu">
    <span class="menuitem" id="previousItem">
        <a class="nav_link">Previous</a>
    </span>
    <span class="menuitem" id="nextItem">
        <a class="nav_link" href="sw_test_2.html">Next</a>
    </span>
</div>

即使surfaceGrp换行发生在列表中间：

<sourceDoc xml:id="TextContent">
    <surfaceGrp xml:id="wall" n="West Wall">
        <surface xml:id="EETS.T.60">
            <label>Verse 60</label>
            <graphic url="ww_test_1.jpg"/>
        </surface>
        <surface xml:id="EETS.T.63">
            <label>Verse 63</label>
            <graphic url="ww_test_2.jpg"/>
        </surface>
        <surface xml:id="EETS.T.65">
            <label>Verse 65</label>
            <graphic url="ww_test_3.jpg"/>
        </surface>
    </surfaceGrp>
    <surfaceGrp xml:id="wall" n="West Wall">
        <surface xml:id="EETS.T.66">
            <label>Verse 66</label>
            <graphic url="ww_test_4.jpg"/>
        </surface>
        <surface xml:id="EETS.T.68">
            <label>Verse 68</label>
            <graphic url="ww_test_5.jpg"/>
        </surface>
        <surface xml:id="EETS.T.69">
            <label>Verse 69</label>
            <graphic url="ww_test_6.jpg"/>
        </surface>
    </surfaceGrp>
</sourceDoc>

修改我的代码以实现此目的的最佳方法是什么？

我的问题仍然不清楚，所以这不是你想要的，但它可能会指出你正确的方向。

这个XSLT 2.0样式表....

<xsl:transform
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="2.0">

<xsl:output method="html" version="5" encoding="UTF-8" indent="yes" />
<xsl:strip-space elements="*" />

<xsl:template match="/">
  <html>

      <title>Source Doc</title>
    </head>
    <body>
      <xsl:apply-templates select="sourceDoc" />
    </body>
  </html>
</xsl:template>

<xsl:template match="sourceDoc">
  <div id="centerMenu">
    <xsl:apply-templates select="surfaceGrp/surface"/>
  </div>
</xsl:template>

<xsl:template match="surface">
  <span class="menuitem" id="{@xml:id}">
    <a class="nav_link" href="{graphic/@url}">
