当特定节点值为 ERROR 时如何计算唯一值。下面是xml源。有不同的数据集,如 SellOut、SellIn 和 Inventory,但我希望 RECORD_TYPE=ERROR 有一个唯一的记录计数,而与数据集类型无关

<SellOutErrorRecord>
    <RECORD_TYPE>WARNING</RECORD_TYPE>
    <ERROR_DESC>record 1:location id is invalid</ERROR_DESC>
    <RECORD_NO>1</RECORD_NO>
    <LOCATION_NAME>XYZ el</LOCATION_NAME>
    <PRODUCT_NUMBER>336549R-001</PRODUCT_NUMBER>
    <PRODUCT_OPTION>0D1</PRODUCT_OPTION>
    <PRODUCT_LINE>LA</PRODUCT_LINE>
</SellOutErrorRecord>
<SalesInErrorRecord>
    <RECORD_TYPE>ERROR</RECORD_TYPE>
    <ERROR_DESC>record 1:location id is invalid</ERROR_DESC>
    <RECORD_NO>1</RECORD_NO>
    <LOCATION_NAME>XYZ el</LOCATION_NAME>
    <PRODUCT_NUMBER>336549R-001</PRODUCT_NUMBER>
    <PRODUCT_OPTION>0D1</PRODUCT_OPTION>
    <PRODUCT_LINE>LA</PRODUCT_LINE>
    <PRODUCT_LINE_TYPE>C</PRODUCT_LINE_TYPE>
</SalesInErrorRecord>
<SellOutErrorRecord>
    <RECORD_TYPE>ERROR</RECORD_TYPE>
    <ERROR_DESC>record 2:SO:invoiced net amount is invalid</ERROR_DESC>
    <RECORD_NO>2</RECORD_NO>
    <LOCATION_NAME>XYZ el</LOCATION_NAME>
    <PRODUCT_NUMBER>3X-KN73C-DB</PRODUCT_NUMBER>
    <PRODUCT_OPTION>0D1</PRODUCT_OPTION>
    <PRODUCT_LINE>HA</PRODUCT_LINE>
    <PRODUCT_LINE_TYPE>E</PRODUCT_LINE_TYPE>
</SellOutErrorRecord>
<SellOutErrorRecord>
    <RECORD_TYPE>ERROR</RECORD_TYPE>

<SalesInErrorRecord>

</SellOutErrorRecord>
<SalesInErrorRecord>
    <RECORD_TYPE>ERROR</RECORD_TYPE>
    <ERROR_DESC>record 5:SI:transaction currency is null or invalid</ERROR_DESC>
    <RECORD_NO>5</RECORD_NO>
    <LOCATION_NAME>XYZ el</LOCATION_NAME>
    <PRODUCT_NUMBER>339112-B25</PRODUCT_NUMBER>
    <PRODUCT_OPTION>0D1</PRODUCT_OPTION>
    <PRODUCT_LINE>J3</PRODUCT_LINE>
    <PRODUCT_LINE_TYPE>E</PRODUCT_LINE_TYPE>
</SalesInErrorRecord>

    <RECORD_NO>6</RECORD_NO>
    <LOCATION_NAME>XYZ XYZ</LOCATION_NAME>
    <PRODUCT_NUMBER>331184-B21</PRODUCT_NUMBER>
    <PRODUCT_OPTION>0S1</PRODUCT_OPTION>
    <PRODUCT_LINE>R8</PRODUCT_LINE>
    <PRODUCT_LINE_TYPE>E</PRODUCT_LINE_TYPE>
</InventoryErrorRecord>
<SellOutErrorRecord>
    <RECORD_TYPE>ERROR</RECORD_TYPE>
    <ERROR_DESC>record 6:SO:invoiced net amount is invalid</ERROR_DESC>
    <RECORD_NO>6</RECORD_NO>
    <LOCATION_NAME>XYZ el</LOCATION_NAME>
    <PRODUCT_NUMBER>339112-B25</PRODUCT_NUMBER>
    <PRODUCT_OPTION>0D1</PRODUCT_OPTION>
    <PRODUCT_LINE>J3</PRODUCT_LINE>
    <PRODUCT_LINE_TYPE>E</PRODUCT_LINE_TYPE>
</SellOutErrorRecord>

输出必须是 record_count=5。谢谢你的帮助...

在 XSLT 1.0 中,区分是相当不直观的。我假设根节点是xml,并且使记录唯一的是RECORD_NO.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="text" indent="no"/>

    <xsl:template match="/xml">
        record_count=<xsl:value-of select="count(*[RECORD_TYPE='ERROR' and not(following::*[RECORD_TYPE='ERROR']/RECORD_NO/text() = RECORD_NO/text())])" />
    </xsl:template>
</xsl:stylesheet>
