简短问题：
为什么我的xsl:accumulator-rule
<xsl:when test="substring($msg, $value, string-length(./TagField/@value)) != ./TagField/@value">不适用于Saxon PE 9.9，但适用于XSL Professional 2020 sp1。撒克逊人报告的错误是：
错误评估（fn：accumulator-before（...）= xsl：when / @ test的第45行第100列中的fn：accumulator-after（...）） format.xslt：XPTY0004：不允许使用空序列，因为 fn：substring（）的第二个参数。在雾化第一个时发现 带有match =“ pattern匹配的模板规则中的'='操作数 node（）/ element（Q {} MessageFormat）/ element（Q {} StructFormat）[（not（attribute :: attribute（Q {} repeat））） 和child :: element（Q {} TagField）]“在format.xslt的第82行 内置模板规则（浅拷贝）调用 由xsl：apply-templates调用在文件：/ D：/issue/pfr-transportevent-v01/config/transformation/xslt/format.xslt#102 在format.xslt的第101行的过程complete-struct中： 由global xsl：variable调用在template规则中，在format.xslt的第104行上具有match =“ /”的值不允许使用空序列作为 fn：substring（）的第二个参数。在雾化第一个时发现 '='的操作数
这是我完整的xsl:accumulator
<xsl:accumulator name="position-count" as="xs:integer?" initial-value="1" streamable="no">
<xsl:accumulator-rule match="$MFL/MessageFormat/StructFormat" phase="end">
<xsl:choose>
<xsl:when test="./@repeat = '*' ">
<xsl:choose>
<xsl:when test="substring($msg, $value, string-length(./TagField/@value)) != ./TagField/@value">
<xsl:sequence select="$value"/>
</xsl:when>
<xsl:otherwise>
<xsl:variable name="repeat" select="count(tokenize(fn:substring($msg, $value) , ./TagField/@value)) - 1"/>
<xsl:sequence select="$value + map:get($groupsize, ./@name) * $repeat"/>
</xsl:otherwise>
</xsl:choose>
</xsl:when>
<xsl:when test="substring($msg, $value, string-length(./TagField/@value)) = ./TagField/@value">
<!--<xsl:sequence select="$value + xs:integer(sum(.//FieldFormat/@length)) + string-length(./TagField/@value)"/>-->
<xsl:sequence select="$value + map:get($groupsize, string(./@name))"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$value"/>
</xsl:otherwise>
</xsl:choose>
</xsl:accumulator-rule>
</xsl:accumulator>
背景：
我必须解决以下问题，例如，输入是长度可变的纯文本

我的XSLT tempalte使用XML Spy Pro 2020 sp1，但是使用saxon 9.9 PE时，我在累加器规则中遇到累加器错误。
我知道Saxon的实现严格遵守W3C XSLT规范，XML Spy Pro通常并不总是如此。我的``累加器规则''有什么问题？
答案 0 :(得分：0)
由于我的帖子过长，因此我必须在此处添加更多文本：
在XML文件中指定生成xml的规则：
