根据与该元素的精确匹配，将数据附加到元素

2023-11-29

给定以下 XML 作为输入，

<?xml version="1.0" encoding="UTF-8"?>
<TABLE NAME="TABLE.DB">
    <DATA RECORDS="2">
        <RECORD ID="4">
            <RECNO>0</RECNO>
            <SEQ>0</SEQ>
            <DATE>17/12/1999 2:44:08 μμ</DATE>

            <NUMBER>10354</NUMBER>
            <CN>PL</CN>
            <PROPERTY>0</PROPERTY>

            <NUMBER>10355</NUMBER>
            <CN>PL</CN>
            <PROPERTY>0</PROPERTY>
            <DAYS>0</DAYS>
            <CURRENTSTATUS>0</CURRENTSTATUS>
            <TOTALS>1</TOTALS>
        </RECORD>
        <RECORD ID="2">
            <RECNO>2</RECNO>
            <SEQUENCE>0</SEQUENCE>
            <DATE>17/12/1999 2:44:08 μμ</DATE>

            <PROPERTY>0</PROPERTY>
            <DAYS>10</DAYS>
            <CURRENTSTATUS>0</CURRENTSTATUS>
            <SUB_A>Some random data not matched.</SUB_A>
        </RECORD>
        <RECORD ID="1">
            <RECNO>3</RECNO>
            <SEQUENCE>0</SEQUENCE>
            <DATE>17/12/1999 2:44:08 μμ</DATE>
            <ID>12/11/2015 3:15:25 μμ</ID>
            <NUMBER>10357</NUMBER>
            <CN>PL 300 L</CN>
            <PROPERTY>0</PROPERTY>
            <DAYS>10</DAYS>
            <CURRENTSTATUS>0</CURRENTSTATUS>
            <TOTALS>19837</TOTALS>
        </RECORD>
        <RECORD ID="0">
            <RECNO>3</RECNO>
            <SEQUENCE>0</SEQUENCE>
            <DATE>17/12/1999 2:44:08 μμ</DATE>
            <ID>12/11/2015 3:15:25 μμ</ID>
            <NUMBER>10358</NUMBER>
            <CN>PL 300 L</CN>
            <PROPERTY>0</PROPERTY>
            <DAYS>10</DAYS>
            <CURRENTSTATUS>0</CURRENTSTATUS>
        </RECORD>
    </DATA>
</TABLE>

以及以下制表符分隔的文件：

[yet another value.]\t10358
value i'd like to add\t10355
(another) value i'd like to add\t10357

我使用 \t 来显示选项卡在文件中的位置。我想将第一列中找到的数据附加到我尝试匹配的元素中，在本例中为 NUMBER。

因此，如果 NUMBER 等于第二列，请使用 | 将第一列中找到的值附加到它后面。作为分隔符。

如何获得以下结果，但保持记录的顺序，对元素输出进行排序：

     <?xml version="1.0" encoding="UTF-8"?>

    <DATA RECORDS="2">
          <RECORD ID="0">

我使用最新的 Saxon，v 9.8


The xsl:merge与您之前的问题类似，要对合并结果进行排序，您可以简单地将xsl:merge进入一个xsl:perform-sort:

<?xml version="1.0" encoding="UTF-8"?>

                                    <xsl:value-of select="NUMBER, current-merge-group()[2]"
                                        separator=" | "/>
