我有 XML 文件
<?xml version="1.0" encoding="ISO-8859-1"?>
<childrens>
<child entity_id="1" value="Root Catalog" parent_id="0">
<child entity_id="2" value="Apparel" parent_id="1">
<child entity_id="4" value="Shirts" parent_id="2"/>
<child entity_id="5" value="Pants" parent_id="2"/>
</child>
<child entity_id="3" value="Accessories" parent_id="1">
<child entity_id="6" value="Handbags" parent_id="3"/>
<child entity_id="7" value="Jewelry" parent_id="3"/>
</child>
.
.
.
<child entity_id='1110' value="test" parent_is="1109">
<child entity_id='1111' value="test0" parent_is="1110">
<child entity_id="1005" value="test1" parent_is="1111"/>
<child entity_id="1006" value="test12" parent_is="1111"/>
<child entity_id="1007" value="test123" parent_is="1111"/>
<child>
</child>
<child >
</childrens>
现在我已经编写了这个 XSL 代码
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes" omit-xml-declaration="yes"/>
<xsl:param name="selected" />
<xsl:template match="/*">
<xsl:apply-templates select="*[not($selected)] | //*[@entity_id = $selected]/*" />
</xsl:template>
<xsl:template match="*">
<span onclick="displayResult('{@entity_id}');">
<xsl:value-of select="concat(@value, ' ')"/><br/>
</span>
</xsl:template>
</xsl:stylesheet>
HTML 是

function loadXMLDoc(dname) {

processor.input = xml;

target.innerHTML = processor.output;
}
function transformOther(xml, xsl, target, selected) {
var xsltProcessor = new XSLTProcessor();

我正在使用此代码来制作树，现在我想要其中的 xsl
1) 我想从特定节点开始，例如这里测试，其中entity_id=1110
2) 叶子元素有一个类似 child 的类，例如，在 value = test 并且 value 的元素的情况下，叶子元素是 test1, test12, test123 =测试0
最佳答案
这个怎么样:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes" omit-xml-declaration="yes"/>
<xsl:param name="defaultValue" select="'test'" />
<xsl:param name="selected" select="//*[@value = $defaultValue]/@entity_id" />
<xsl:template match="/*">
<xsl:apply-templates select="*[not($selected)] | //*[@entity_id = $selected]/*" />
</xsl:template>
<xsl:template match="*">
<span onclick="displayResult('{@entity_id}');">
<xsl:if test="not(*)">
<xsl:attribute name="class">leaf</xsl:attribute>
</xsl:if>
<xsl:value-of select="concat(@value, ' ')"/><br/>
</span>
</xsl:template>
</xsl:stylesheet>
如果将 select 属性添加到 xsl:param，则可以指示要用作的项目的 entity_id默认起始项。
第二个模板中的 xsl:if 会将 class="leaf" 属性添加到叶节点。
