我需要在pdf文件的菜单中建立一个链接，我收到此错误。

发生错误

在XSLT解析时，此错误在Umbraco中很常见，因为解析器假定您的某些数据可能为空/空，而实际上它可能[总是]已分配。

诀窍是找到罪魁祸首的代码行并将其封装为test-for-empty-if-block。

例如，它可能是也可能不是这一行，尽管它常见于@id和NiceUrl()：

<xsl:otherwise>
    <xsl:if test="@id != ''">
        <a href="{umbraco.library:NiceUrl(@id)}">
            <xsl:value-of select="@nodeName"/>
        </a>
    </xsl:if>
</xsl:otherwise>

错误可能来自GetMedia() ¹或NiceUrl() ²调用，因为它们需要传递Int32类型的参数，但是我可以看到你已经在if-block中附上了GetMedia()来电。
