In general, when we take out a set of data, we like to put the data into a table, which facilitates data comparison and reading. But XSL does not provide a mechanism for any
Meaning of the group. So you have to use Xsl:if to combine the context () to do this work. The following example returns a two-column table.
<table border= "1" >
<xsl:for-each select= "Singers/singer" >
<xsl:if expr= "(childnumber (this)% 2) = = 1" >
<TR>
<td><xsl:value-of/></td>
<td><xsl:value-of select= ". /singer[index () $gt $ context ()!index ()][0] "/></td>
</TR>
</xsl:if>
</xsl:for-each>
</TABLE>
If you're going to go back to a three-column example, you'll need to add a new, similar code that only generates a new row for every three elements. From this you can infer a need
How the table for n columns is implemented.
<table border= "1" >
<xsl:for-each select= "Singers/singer" >
<xsl:if expr= "(childnumber (this)% 3) = = 1" >
<TR>
<td><xsl:value-of/></td>
<td><xsl:value-of select= ". /singer[index () $gt $ context ()!index ()][0] "/></td>
<td><xsl:value-of select= ". /singer[index () $gt $ context ()!index ()][1] "/></td>
</TR>
</xsl:if>
</xsl:for-each>
</TABLE>
