I apologise for the delay, and hope you're still willing to help me.

I understand you need more details about my script and resources, here they are :

- 8Go RAM (that is a problem for me now, as I tend to write quite greedy code, I'm getting out of memory errors)

- a 70Ko XML file, almost 2M lines long, each line corresponding to one word / node, like this : 

<DocumentSet>
<document>
<w lemma="appeler" type="VER:pres">appelle</w>
<w lemma="quand" type="KON">quand</w>
<w lemma="gronder" type="VER:infi">gronder</w>
</document>
</DocumentSet>

- a 10 Ko tabulation separated text file, 150k lines long, looking like this :

I'm using the XML::Twig module to go through the XML tree and modify nodes. I use a foreach $w instruction to loop through each <w> node and then check if its content matches a word from the first column of the tab document. If so, I want to add some attributes from the other columns to the XML node for a result like this : 
<w conjugaison="imp:pre:2s;ind:pre:1s;ind:pre:3s;sub:pre:1s;sub:pre:3s
+;" genre="" lemma="appeler" nombre="" type="VER:pres">appelle</w>

    <w genre="" lemma="quand" nombre="" type="KON">quand</w>

    <w conjugaison="inf;" genre="" lemma="gronder" nombre="" type="VER
+:infi">gronder</w>
