XSLT：将一个字符串连接n次

Question

I want to concatenate a string for n times and set it as variable using XSLT 2.0. The string to be concatenated is ../ , n is available as number in a variable.

I tried:

<xsl:variable name="count-dirs" select="count(tokenize($target-filepath, '/')) - 1"/>
<xsl:variable name="path" select="''"/>
<xsl:for-each select="1 to $count-dirs"><xsl:variable name="path" select="concat($path, '../')"/></xsl:for-each>

Answer 1

I think you want eg <xsl:variable name="path" select="string-join((1 to $count-dirs).'.,/', '')"/> in XSLT 3 or <xsl:variable name="path" select="string-join(for $i in 1 to $count-dirs return '../', '')"/> in XSLT 2.

Answer 2

Life can be so easy...

<xsl:variable name="count-dirs" select="count(tokenize($target-filepath, '/')) - 1"/>
<xsl:variable name="path">
    <xsl:for-each select="1 to $count-dirs">../</xsl:for-each>
</xsl:variable>
