我正在创建一个集成，以在从输入文件中获取详细信息之后，将包含多行的供应商发票加载到工作日。直到我在XSLT的Web服务请求中添加累加器逻辑以首先检查成本中心是否存在于工作日，一切似乎都按预期进行。如果是，那么我将填充其他值，我需要填充默认值。如果地图中还不存在成本中心，我还没有建立默认逻辑。
我创建了一个自定义报告，以获取所有活动成本中心，并将此列表与输入文件合并。
将自定义报告与输入文件合并后的样本数据-

下面是我正在工作的XSLT，即在添加累加器逻辑之前-

但是当我在XSLT上面的累加器逻辑下面添加内容时，Studio出错了
<xsl:mode streamable="yes" on-no-match="shallow-skip" use-accumulators="CostCenterLookup CurrentLookupValue"/>
<xsl:output method="xml"/>
<xsl:accumulator name="CurrentLookupValue" as="xs:string" initial-value="''" streamable="yes">
<xsl:accumulator-rule match="wd:CostCenter1/text()" select="."/>
</xsl:accumulator>
<xsl:accumulator name="CostCenterLookup" as="map(xs:string,xs:string)" initial-value="map{}" streamable="yes">
<xsl:accumulator-rule match="wd:CostCenter2/text()" select="map:put($value, accumulator-before('CurrentLookupValue'), string(.))"/>
</xsl:accumulator>
<xsl:value-of select="accumulator-before('CostCenterLookup')( normalize-space( substring(col17,1,5) ) )"/>
我遇到的错误对于调试确切的问题不是很有帮助-
提交供应商发票申请失败，为null。调用期间发生错误：null
真的很感谢您的帮助。
答案 0 :(得分：0)
我想该错误仅是由于尝试使用流式传输（如您在xsl:mode上声明）和xsl:for-each-group select="root/row" group-by="col2"引起的。使用流式传输时，您无法访问row表达式中填充元素的子元素（即group-by元素），因为这将需要处理（消耗）每个row的内容。因此，您将需要使用xsl:for-each-group select="root/row!copy-of()" group-by="col2"。否则，处理器将拒绝样式表代码为不可流式处理。您可能想要尝试从命令行使用Saxon EE进行验证，这样肯定可以提供更好的诊断。
