我需要将所有 xlink 用法替换为SVG中的简单内联xml，然后删除＆＃34; defs ＆＃34;部分并删除所有 boo ：属性。需要这个是因为要使用的SVG查看器不支持xlinks。
初始简化XML
<?xml version="1.0" encoding="utf-8"?>
<svg xmlns="http://www.w3.org/2000/svg">
<boo:metadata>
<boo:text line-space="1.5" minimum-size="15" regular-size="20"/>
</boo:metadata>
<g transform="translate(149,60)">
<rect x="0" y="0" fill-opacity="0.6" width="579" height="150"/>
<defs><!-- huge section with predefined items-->
<g id="ne">
<path id="ne..."/>
</g>
<g id="nw">
<path id="nw.."/>
</g>
<g id="rt2">
<rect id="RT2" />
<path id="some cool path id"/>
</g>
<g id="rt3">
<rect id="rt3sss" rx="2" ry="2"/>
</g>
<g boo:type="Icon" id="AIRPORT" boo:replacementWords="FLUGHAFEN">
<rect id="ICON_AIRPORT" fill="#FCFFFF" height="15" width="15"/>
<path id="ICON_AIRPORTPATH"/>
</g>
</defs>
<g boo:side="R" id="sssss" transform="translate(184,0)">
<g transform="translate(0.000000,0.000000)">
<g boo:style="HorizontalAlignment:Center;VerticalAlignment:Bottom;" transform="translate(63.202000,126.903002)">
<g transform="translate(0.000000,0.000000)">
<!-- actual usage -->
<use xlink:actuate="onLoad" xlink:type="simple" xlink:show="embed" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#NE" boo:style="HorizontalAlignment:Left;"/>
</g>
<g transform="translate(23.045999,0.000000)" boo:style="HorizontalAlignment:Left;Margin:0 5 0 5;">
<g transform="translate(0.000000,0.000000)" boo:style="Margin:0 1 0 1;">
<g transform="scale(1.150000,1.1500000)">
<!-- actual usage -->
<use xlink:actuate="onLoad" xlink:type="simple" xlink:show="embed" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#RT2"/>
</g>
<text transform="translate(16,13)" text-anchor="middle">4</text>
</g>
</g>
</g>
</g>
</g>
</g>
</svg>

我自己解决了这个问题。这里的主要复杂因素是XSL模板中的命名空间使用不正确。
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:boo="..." xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:svg="http://www.w3.org/2000/svg">
<!-- copy everything as is -->
<xsl:template match="@*|node()" name="identity">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<!-- replace xlink uses to real svg objects -->
<xsl:template match="svg:use">
<xsl:copy-of select="/*/*/*/*[@id=substring(current()/@xlink:href, 2)]"/>
</xsl:template>
<!-- remove unneeded defs section -->
<xsl:template match="svg:defs"/>
<!-- remove all unneeded cjv nodes and attributes -->
<xsl:template match="@boo:*"/>
<xsl:template match="boo:*"/>
<!-- remove comments and whitespaces -->
<xsl:strip-space elements="*"/>
<xsl:template match="comment()"/>
<!-- EXPERIMENTAL - remove id and type attributes -->
<xsl:template match="@id"/>
<xsl:template match="@type"/>
</xsl:stylesheet>

Better path would be
<xsl:template match="svg:use">
<xsl:copy-of select="//*[@id=substring(current()/@xlink:href, 2)][1]"/>
</xsl:template>
'//*' matches, from the root, any descendant at any depth. the terminal '[1]' says that if there should happen to be two nodes with the specified id (which there should not be), choose the first.
In my own attack on this problem I also wanted to give the newly copied element the id of the replaced use element, but that proved tricky so I wrapped a g round it:
<xsl:template match="svg:use">
<g>
<!-- copy id, transform, etc through from use reference -->
<xsl:apply-templates select="@*"/>
<xsl:copy>
<xsl:apply-templates select="//*[@id=substring(current()/@xlink:href, 2)][1]"/>
</xsl:copy>
</g>
</xsl:template>
Finally, when you copy a template, you copy all the ids of all the elements in them, and, if you have multiple copies of a symbol as I do, that's a bad thing. So I translated all ids to classes:
<!-- generally, change ids to classes -->
<xsl:template match="@id">
<xsl:attribute name="class">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:template>
Obviously I'm using xsl:copy rather than xsl:copy-of so that these fixes will work. There is a problem with my code - it wraps a spurious no-attributes use element around my generated g element - but it renders OK.
