为什么我的标签在XSLT转换后扩展（以及如何修复）？

我有来自SQLServer的XML . 我无法让SQLServer让我有条件地更改节点的名称，所以我稍后使用XSLT进行操作 . 我真的不知道我在使用XSLT做什么 - 我已经从我在StackOverFlow上搜索的内容中拼凑了我的解决方案 . 我遇到的问题是，在输入中没有子节点的标签（因此只有一个标签）被扩展为在转换后具有开始和结束标记 . 我想阻止这一点，因为我们有足够的用户，带宽是一个问题 .

输入是：

XSLT是

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">
    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>
    <xsl:template match="content_block">
        <xsl:element name="{@type}">
        <xsl:apply-templates select="@*|node()"></xsl:apply-templates>
        </xsl:element>
    </xsl:template>
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

......输出是：

请注意每个问号标签现在是如何“爆炸”的 . 在真正的XML中，有很多东西比我在这里展示的要多得多 .

将这个问题放在一起时我注意到的一件事是，转换也是为转换后的XML添加UTF-16编码 . 如果有人对如何解决这个问题有任何想法，那也欢迎:) .

Update
我已经设法通过在结果字符串上使用Replace来修复UTF编码，但我对解决方案并不满意 .
