Question

Given the following XML as input,
<?xml version="1.0" encoding="UTF-8"?>
<TABLE NAME="TABLE.DB">
<DATA RECORDS="2">
<RECORD ID="4">
<RECNO>0</RECNO>
<SEQ>0</SEQ>

<ID>12/11/2015 3:15:25 μμ</ID>
<NUMBER>10357</NUMBER>
<CN>PL 300 L</CN>
<PROPERTY>0</PROPERTY>

<CN>PL 300 L</CN>
<PROPERTY>0</PROPERTY>
<DAYS>10</DAYS>
<CURRENTSTATUS>0</CURRENTSTATUS>
</RECORD>
</DATA>
</TABLE>
and the following tab separated file:
[yet another value.]\t10358
value i'd like to add\t10355
(another) value i'd like to add\t10357
i used \t, in order to show where the tab exists in the file. i would like to append the data found in the first column, into the element i try to match on, which in this case in NUMBER.
So if NUMBER equals second column, append to it the value found in the first column, using | as a separator.
how one could have the below result, but with keeping the order of the records, sorting on the element Output:
<?xml version="1.0" encoding="UTF-8"?>
<TABLE NAME="TABLE.DB">
<DATA RECORDS="2">
<RECORD ID="0">

The xsl:merge is similar to your previous question and to sort the merge result you can simply wrap the xsl:merge into an xsl:perform-sort:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:template match="TABLE/DATA">

<xsl:merge-source name="line" select="$lines" sort-before-merge="yes">
