Does xpath query has Limit option like mysql

Question

I want to limit number of result I receive from xpath query.

For example:-

$info = $xml->xpath("//*[firstname='Sheila'] **LIMIT 0,100**"); 

You see that LIMIT 0,100.

Answer 1

You should be able to use "//*[firstname='Sheila' and position() <= 100]"

Edit:

Given the following XML:

<root> 
    <country.php desc="country.php" language="fr|pt|en|in" editable="Yes"> 
        <en/> 
        <in> 
            <cityList desc="cityList" language="in" editable="Yes" type="Array" index="No"> 
                <element0>Abu</element0>
                <element1>Agartala</element1>
                <element2>Agra</element2> 
                <element3>Ahmedabad</element3>
                <element4> Ahmednagar</element4> 
                <element5>Aizwal</element5>
                <element150>abcd</element150> 
            </cityList> 
        </in> 
    </country.php> 
</root>

You can use the following XPath to get the first three cities:

//cityList/*[position()<=3]

Results:

Node    element0    Abu
Node    element1    Agartala
Node    element2    Agra

If you want to limit this to nodes that start with element:

//cityList/*[substring(name(), 1, 7) = 'element' and position()<=3]

Note that this latter example works because you're selecting all the child nodes of cityList, so in this case Position() works to limit the results as expected. If there was a mix of other node names under the cityList node, you'd get undesirable results.
For example, changing the XML as follows:

<root> 
    <country.php desc="country.php" language="fr|pt|en|in" editable="Yes"> 
        <en/> 
        <in> 
            <cityList desc="cityList" language="in" editable="Yes" type="Array" index="No"> 
                <element0>Abu</element0>
                <dog>Agartala</dog>
                <cat>Agra</cat> 
                <element3>Ahmedabad</element3>
                <element4> Ahmednagar</element4> 
                <element5>Aizwal</element5>
                <element150>abcd</element150> 
            </cityList> 
        </in> 
    </country.php> 
</root>

and using the above XPath expression, we now get

Node    element0    Abu

Note that we're losing the second and third results, because the position() function is evaluating at a higher order of precedence - the same as requesting "give me the first three nodes, now out of those give me all the nodes that start with 'element'".
