Umbraco XSLT-检索节点'；页面图像'；上市时

我的网站上有一个新闻页面，它列出了宏中的所有子页面（新闻文章）

每个子页面都有一个图像（别名pageImage）

我有以下XSLT代码，但它不起作用：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
    version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:msxml="urn:schemas-microsoft-com:xslt" 
    xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" 
    exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">

<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:template match="/">

<!-- The fun starts here -->
<ul id="reports">
<xsl:for-each select="$currentPage/node [string(data [@alias='umbracoNaviHide']) != '1']">
<xsl:sort select="@createDate" order="descending" />
    <li>
        <img>
            <xsl:attribute name="src">
                <xsl:text>/umbraco/ImageGen.ashx?image=</xsl:text>
                <xsl:value-of select="umbraco.library:GetMedia(data[@alias='pageImage'],'true')/data[@alias='umbracoFile']"/>
                <xsl:text>&amp;width=125&amp;height=125&amp;constrain=true&amp;pad=true&amp;BgColor=white&amp;transparent=false</xsl:text>
            </xsl:attribute>
            <xsl:attribute name="alt">
                <xsl:value-of select="something"/>
            </xsl:attribute>
        </img>
        <h2><a href="{umbraco.library:NiceUrl(@id)}"><xsl:value-of select="@nodeName"/></a></h2>
        <p class="date"><xsl:value-of select="data [@alias = 'date']" disable-output-escaping="yes"/></p>
        <p>Mauris sit amet augue ut felis blandit placerat. Sed tempus gravida libero. Donec placerat lacus 
        eget neque. Mauris sit amet augue ut felis blandit placerat. Sed tempus gravida libero.</p>
        <p><a><img src="images/pdf.gif" alt="Download/view PDF" align="left" /> Download/View PDF</a> - 82kb</p>
    </li>
</xsl:for-each>
</ul>

</xsl:template>

</xsl:stylesheet>

有人知道怎么回事吗？我知道这与

行有关，就像我硬编码一个图像URL一样，它工作正常

谢谢

调用需要一个整数作为第一个参数。将

数据[@alias='pageImage']

的值转换为Int32时，似乎会发生此错误

查看getMedia如何工作的详细说明。

您使用的是什么版本的Umbraco？
