I have the following XML code:

<n-grams-sorted analysis="N_GRAM_TOKEN2" range="Total Set" types="33459" tokens="50285">
    <n-gram position="1" frequency="387" probability="0.0077">x =</n-gram>
    <n-gram position="2" frequency="319" probability="0.00634">! =</n-gram>
    <n-gram position="3" frequency="295" probability="0.00587">= [i]</n-gram>
    <n-gram position="4" frequency="286" probability="0.00569">? =</n-gram>
    <n-gram position="5" frequency="221" probability="0.00439"> love

=</n-gram>
<n-gram position="6" frequency="186" probability="0.0037">. =</n-gram>
<n-gram position="7" frequency="182" probability="0.00362">:p =</n-gram>

....

<n-gram position="90" frequency="25" probability="0.0005">? :p</n-gram>

How do you get the first 30 with a <xsl:for-each> ?

<xsl:for-each select="//n-gram[@position < $position]">

Hi KevinDW,

1.) Nice smilie in your code! lol

2.) This does not work this way. It seems the only way is to use a recursive template.
Found this snippet:

CODE

<xsl:template name="recurse_till_ten">
    <xsl:param name="num">1</xsl:param> 
    <xsl:if test="not($num = 10)">
        ...do something
        <xsl:call-template name="recurse_till_ten">
            <xsl:with-param name="num">
                <xsl:value-of select="$num + 1">
            </xsl:with-param>
        </xsl:call-template>
    </xsl:if>
</xsl:template>

Source: http://sourceware.org/ml/xsl-list/2000-08/msg01503.html

Adjust from 10 to 30 and put your processing code at the do something position.

Hope this helps.

Cheers,

Hey MakeItSo,

Your code helps me a lot.

But I have just one little question:

I want to select "position"
from

<n-gram position="1" frequency="387" probability="0.0077">x =</n-gram>

with

<xsl:value-of select="./position"/>

But it's not correct?
Do you know the solution for this one?

Hi Kevin,

"position" is an aatribut, so you need to address it as "@position"
