Question

Answer 1

+1 A:

I think what you might be looking for is something along the lines of

[position() > 2]

which retrieves all elements after the first two.

Perfect! Thank you.Could I use?[position() = 1][position() = 4]if i want to get only the first and the fouth element?

@Damiano - If you evaluate those two predicate filters separately, you will get the information you want. If you want to evaluate them in a single XPATH expression, then you will need to combine them in a single predicate filter and use the `or` operator: `[position()=1 or position()=4]` Otherwise, it will evaluate to see if both predicate filters are true(and no element will be both the 1st AND the 4th).

Answer 2

A:

First notice that the provided XML is not well-formed!

I assume that intended wellformed XML more or less looks like this:

<table>
    <tr>
        <td class="data1"><p>1</p></td>
        <td class="data1"><p>2</p></td>
        <td class="data1"><p>3</p></td>
        <td class="data1"><p>4</p></td>
    </tr>
    <tr>
        <td class="data1"><p>5</p></td>
        <td class="data1"><p>6</p></td>
        <td class="data1"><p>7</p></td>
        <td class="data1"><p>8</p></td>
    </tr>
</table>

For this XML document here are my answers.

Use:

/*/*/td[position() = 3 or position() = 4]/p

Or, you can use the XPath union operator:

/*/*/td[3]/p | /*/*/td[4]/p

The following is wrong:

/*/*/td[3] [4]/p

This specifies the selection of 4th node of /*/*/td[3] and will select nothing because /*/*/td[3] only selects two nodes.

Lastly, here is a transformation that when run demonstrates the result of all XPath expressions above:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt;
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="/">
  <xsl:copy-of select=" /*/*/td[position() = 3 or position() = 4]/p"/>

  ----------------------

  <xsl:copy-of select="   /*/*/td[3]/p  | /*/*/td[4]/p"/>

  ----------------------

  <xsl:copy-of select=" /*/*/td[3][4]/p"/>

 </xsl:template>
</xsl:stylesheet>
