Hi,
how can i change only one attribute in XLST ?
Like if i have
<node a="test" b="something" c="hello"></node>
I want to change everything that has a hello, to bye, but mantain the other attributes untouched, so the output would be
<node a="test" b="something" c="bye"></node>
The problem is i don't know how many attributes will the node have, if it'll have only a,b and c, or a,b,c,d,e,f,g....
So i can't just "hardcode" the @a and @b attributes, and only change the c
thank you

Write a template rule for any attribute
<xsl:template match="*">
<xsl:copy/>
</xsl:template>
and another to change the c attribute
<xsl:template match="c">
<xsl:attribute name="c">bye</xsl:attribute>
</xsl:template>
and then apply-templates to all attributes:
<xsl:template match="node">
<xsl:copy>
<xsl:apply-templates select="@*"/>
</xsl:copy>
</xsl:template>
Alternatively, you can exploit the fact that if you write the same attribute twice, the second one wins:
<xsl:copy-of select="@*"/>
<xsl:attribute name="c">bye</xsl:attribute>
But that doesn't work if you want to delete one attribute.
