[Solved] Replace xml attribute values with constant values by xsl

by


There are a few things incorrect with your XSLT:

  • It is trying to replace the whole ‘use’ element with an attribute.
  • You are using two pairs of quotes around $blue, which causes it to be treated as a string.
  • You are not using namespaces even though your XML uses a namespace.

Please try this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:svg="http://www.w3.org/2000/svg">
    <xsl:output method="xml" indent="yes" encoding="UTF-8"/>
    <xsl:param name="blue" select="'#00f'"/>
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

  <xsl:template match="svg:g[svg:text = "ProcessOutbound"]/svg:use/@fill">
        <xsl:attribute name="fill">
            <xsl:value-of select="$blue"/>
        </xsl:attribute>
    </xsl:template>
</xsl:stylesheet>

When run on your sample input, the result is:

<svg xmlns:xlink="...">
    <g transform="translate(113.63-359.13)">
        <use xlink:href="#D" fill="#00f" />
        <g transform="translate(72.59-8.504)">
            <use xlink:href="#E" xmlns:xlink="x" />
            <path fill="#f00" d="m6.04 526.26h19.843v4.961h-19.843z" stroke-width=".24" stroke-linecap="round" stroke-linejoin="round" stroke="#000" />
            <use xlink:href="#F" />
        </g>
        <text font-family="Arial" fill="#000" font-size="8" y="527.6" x="20.41">ProcessOutbound</text>
    </g>
</svg>
