HTML table: Expand rowspan and colspan values as entries to validate table using XSLt
Question
I hope you have a beautiful day. I'm creating an XSLT code to validate html table is properly structured or not. To validate the table, first I have to expand rowspan and colspan values as each entries "td" in respective rows. Finally, I will check each rows "td" count against "cols" count.
My HTML table is
<table-wrap id="tbl1" position="float">
<label>Table 1</label>
<caption>
<p></p>
</caption>
<alternatives>
<graphic xmlns:xlink="http://www.w3.org/1999/xlink"/>
<table frame="hsides">
<colgroup>
<col align="left"/>
<col align="left"/>
<col align="left"/>
<col align="left"/>
<col align="left"/>
<col align="left"/>
<col align="left"/>
</colgroup>
<thead>
<tr>
<th rowspan="2" align="left">1</th>
<th colspan="5" align="center">2</th>
<th rowspan="2" align="center">3</th>
</tr>
<tr>
<th align="center">4</th>
<th align="center">5</th>
<th align="center">6</th>
<th align="center">7</th>
<th align="center">8</th>
</tr>
</thead>
<tbody>
<tr>
<td>9</td>
<td rowspan="2">10</td>
<td>11</td>
<td>12</td>
<td>13</td>
<td>14</td>
<td rowspan="2">15</td>
</tr>
<tr>
<td>16</td>
<td>17</td>
<td>18</td>
<td>19</td>
<td>20</td>
</tr>
<tr>
<td>21</td>
<td colspan="2">22</td>
<td rowspan="2">23</td>
<td colspan="2">24</td>
<td>25</td>
</tr>
<tr>
<td>26</td>
<td>27</td>
<td>28</td>
<td>29</td>
<td>30</td>
<td>31</td>
</tr>
<tr>
<td rowspan="2">32</td>
<td colspan="2">33</td>
<td>34</td>
<td colspan="2">35</td>
<td rowspan="2">36</td>
</tr>
<tr>
<td rowspan="2">37</td>
<td>38</td>
<td>39</td>
<td>40</td>
<td>41</td>
</tr>
</tbody>
</table>
</alternatives>
</table-wrap>
my XSLT code is
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="table">
<table>
<xsl:apply-templates select="thead"/>
<xsl:apply-templates select="tbody"/>
</table>
</xsl:template>
<xsl:template match="thead">
<thead>
<xsl:apply-templates select="tr"/>
</thead>
</xsl:template>
<xsl:template match="tbody">
<tbody>
<xsl:apply-templates select="tr"/>
</tbody>
</xsl:template>
<xsl:template match="tr">
<xsl:variable name="current-row" select="position()"/>
<xsl:for-each select="td[@rowspan > 1]">
<xsl:variable name="current-col" select="position()"/>
<xsl:variable name="rowspan-value" select="@rowspan"/>
<xsl:for-each select="1 to $rowspan-value">
<xsl:variable name="next-row" select="$current-row + (position() - 1)"/>
<xsl:variable name="col-value" select="."/>
<xsl:variable name="colspan-value" select="@colspan"/>
<xsl:for-each select="1 to $colspan-value">
<xsl:variable name="col-position" select="$current-col + (position() - 1)"/>
<xsl:variable name="row-tag" select="count(../preceding-sibling::tr[position() lt $next-row]) + 1"/>
<xsl:variable name="col-tag" select="count(./td[position() lt $col-position]) + 1"/>
<xsl:element name="td">
<xsl:value-of select="$col-value"/>
</xsl:element>
</xsl:for-each>
</xsl:for-each>
</xsl:for-each>
<xsl:for-each select="td[@colspan > 1]">
<xsl:variable name="current-col" select="position()"/>
<xsl:variable name="colspan-value" select="@colspan"/>
<xsl:for-each select="1 to $colspan-value">
<xsl:variable name="col-position" select="$current-col + (position() - 1)"/>
<xsl:variable name="col-value" select="."/>
<xsl:variable name="row-tag" select="count(../preceding-sibling::tr) + 1"/>
<xsl:variable name="col-tag" select="count(./td[position() lt $col-position] + 1)"/>
<xsl:element name="td">
<xsl:value-of select="$col-value"/>
</xsl:element>
</xsl:for-each>
</xsl:for-each>
<xsl:for-each select="td">
<xsl:if test="not(@rowspan) and not(@colspan)">
<xsl:copy-of select="."/>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
I want the output like <th rowspan="2" align="left">1</th> and <th rowspan="2" align="center">3</th> as <th align="left">1< /th> and <th align="center">3</th> in first and second rows of <tr>
Similarly, <td colspan="2">22</td> as <td>22</td><td>22</td> two td tags based on value mentioned in it
Expected output:
<table-wrap id="tbl1" position="float">
<label>Table 1</label>
<caption>
<p></p>
</caption>

To give you a start using xslt 2.0 :
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:output indent="yes"/>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="table">
<xsl:variable name="colcount" select=" count(colgroup/col)"/>
<table>
<xsl:apply-templates>
<xsl:with-param name="colcount" select="$colcount" />
</xsl:apply-templates>
</table>
</xsl:template>
<xsl:template match="thead|tbody">
<xsl:param name="colcount"/>
<xsl:copy>
<xsl:variable name="entryCheck" as="element()*">
<xsl:apply-templates select="tr"/>
</xsl:variable>
<xsl:variable name="entryCountCheck" select="count($entryCheck)"/>
<xsl:variable name="entryCountShouldBe" select="$colcount * count(tr)"/>
<xsl:attribute name="entryCountShouldBe" select="$entryCountShouldBe"/>
<xsl:attribute name="entryCountCheck" select="$entryCountCheck"/>
<xsl:attribute name="isVald" select="$entryCountShouldBe=$entryCountCheck"/>
<xsl:copy-of select="$entryCheck"/>
</xsl:copy>
</xsl:template>
<xsl:template match="tr">
<xsl:for-each select="*">
<xsl:variable name="current-col-name" select="local-name()"/>
<xsl:variable name="current-col-pos" select="position()"/>
<xsl:variable name="col-value" select="text()"/>
<xsl:variable name="rowspan-value" select="if(@rowspan) then @rowspan else 1"/>
<xsl:variable name="colspan-value" select="if(@colspan) then @colspan else 1"/>
<xsl:for-each select="1 to $rowspan-value">
<xsl:for-each select="1 to $colspan-value">
<xsl:element name="{$current-col-name}">
<xsl:value-of select="$col-value"/>
</xsl:element>
</xsl:for-each>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
will give you this result:
