I made a template for replacing strings with translated value using

But since there usually over 10 strings that have to be translated on
a single page, I think it's not efficient to call document('') 10
times.

False ... the processor is obliged to cache the document tree created by the document() function.

Is there a way to copy the value of document('')/*/trans:tr to a
variable and then access that variable 10 times?
Can a variable hold the node set?

Yes:

<xsl:variable name="trs" select="document('')/*/trans:tr"/>

Would this make sense?

Yes because then you aren't traversing the in-memory tree. So you may be saving time on accessing the tree, but you won't be saving time on accessing the document.

If yes, then how can I change this template?

From the snippet I see I would make the variable $trs (above) global.

Or even go one level farther down the tree:

<xsl:variable name="trstrings" select="document('')/*/trans:tr/tr_string"/>

Then:

<xsl:value-of select="$trstrings[@str=$str]/*[local-name()=$toLang]"/>

I hope this helps.
