我正在尝试使用模板将字符串'REPORT_BLANK'替换为默认值“”。它似乎适用于'Status'属性（在xsl输出中），但是，对于'PayGroup'attirbute，我得到包含'＆amp; #x'字符和来自我不需要的元素的数据的意外输出。请帮助这个新手。

答案 0 :(得分：0)
正在发生的事情是text()的所有InterfaceData个后代都在您的属性中输出。这包括空格和换行符。
如果您将<xsl:strip-space elements="*"/>添加为xsl:stylesheet的子项，则会看到新行的十六进制引用以及空格被删除。但是，该值似乎仍然不正确。
我认为这是因为您在名为current()的模板中对模板string-replace-all的调用中使用了CGIelementToAttribute。
尝试更改此内容：
<!-- output 'REPORT BLANK' as the attribute value -->
<xsl:when test="(contains('|REPORT_BLANK|', concat('|', $myVarElementValue, '|')))">
<xsl:attribute name="{$myVarElementName}">
<xsl:call-template name="string-replace-all">
<xsl:with-param name="text" select="current()"/> <!-- THIS LINE -->
<xsl:with-param name="replace" select="'REPORT_BLANK'"/>
<xsl:with-param name="by" select="''"/>
</xsl:call-template>
</xsl:attribute>
</xsl:when>
到此：
<!-- output 'REPORT BLANK' as the attribute value -->
<xsl:when test="(contains('|REPORT_BLANK|', concat('|', $myVarElementValue, '|')))">
<xsl:attribute name="{$myVarElementName}">
<xsl:call-template name="string-replace-all">
<xsl:with-param name="text" select="$myVarElementValue"/> <!-- THIS LINE -->
<xsl:with-param name="replace" select="'REPORT_BLANK'"/>
<xsl:with-param name="by" select="''"/>
</xsl:call-template>
</xsl:attribute>
</xsl:when>
您可能还需要替换：
<xsl:with-param name="by" select="''"/>
使用：
<xsl:with-param name="by" select="'REPORT BLANK'"/>
否则您的属性值将为空。这是基于xsl:when之前的评论。 （<!-- output 'REPORT BLANK' as the attribute value -->）
另外，如果您真的使用的是XSLT 2.0处理器，为什么不使用replace()函数而不是命名模板？
