-- [求助]在xsl:attribute中使用xsl:value-of的问题
在利用jaxp进行转换的时候遇到一个问题，有一个如下所示的xml：
<users>
<name choosed="true">张三</name>
<name choosed="true">李四</name>
<name choosed="false">王麻子</name>
</users>
希望将其转化成如下所示的xhtml
<!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>查询结果</title>
</head>
<body>
<span>请选择</span>
<form method="post" action="training4.xhtml"> <input name="userName" type="checkbox" checked="checked"
value="张三" />
张三
<br />
<input name="userName" type="checkbox" checked="checked"
value="李四" />
李四
<br />
<input name="userName" type="checkbox" value="王麻子" />
王麻子
<br />
<hr />
<p />
<input value="继续查找" name="isContinue" type="checkbox" />
继续查找
<input type="text" name="Text" />
<br />
<input value="确定" name="Submit" type="submit" />
<p />
</form>
</body>
</html> xslt如下所示:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" encoding="utf-8"
doctype-public="-//W3C//DTD XHTML

doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
indent="yes" />
<xsl:template match="/">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>查询结果</title>
</head> <body>
<span>请选择</span>
<form action="training4.xhtml" method="post"> <xsl:if test="//isMultiChoose='true'">
<xsl:for-each select="//name">
<input type="checkbox" name="userName">
<xsl:attribute name="value">
<xsl:value-of select="self::node()" />
</xsl:attribute>
<xsl:if
test="self::node()[@choosed='true']">
<xsl:attribute name="checked">checked</xsl:attribute>
</xsl:if>
</input>
<xsl:value-of select="self::node()" />
<br />
</xsl:for-each>
<hr />
<p />
<input type="checkbox" name="isContinue"
value="继续查找" />继续查找<input name="Text" type="text" />
<br />
</xsl:if>
<xsl:if test="//isMultiChoose='false'">
<xsl:for-each select="//name">
<input type="radio" name="userName" />
<xsl:attribute name="value">
<xsl:value-of select="self::node()" />
</xsl:attribute>
<xsl:value-of select="self::node()" />
<br />
</xsl:for-each>
<hr />
<p />
<input type="checkbox" name="isContinue"
value="重新查找" />
重新查找
<input name="Text" type="text" />
<br />
</xsl:if>
<input type="submit" name="Submit" value="确定" />
<p />
</form>
</body>
</html>
</xsl:template>
</xsl:stylesheet> 我的目的是想把用户名称作为input的value属性加进去，但是用jaxp运行的时候抛出如下错误：

at com.holleyinfo.notesAgent.Test.main(Test.java:54) 我的java程序是：
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource; public class Test { public static void main(String[] args) throws Exception {
TransformerFactory factory = TransformerFactory.newInstance();
Source xmlSource = new StreamSource("SearchAgain.xml");
Source xlsSource = new StreamSource("查询结果样式表.xsl");
Transformer transformer = factory.newTransformer(xlsSource);
transformer.transform(xmlSource, new StreamResult(System.out)); } } 但是如果把<xsl:attribute name="value">
<xsl:value-of select="self::node()" />
</xsl:attribute>
改为
<xsl:attribute name="value">test</xsl:attribute>
程序运行良好，所以我怀疑是不是由于相同节点名的节点数目比较多导致这个问题，因为我测试如果换成单节点就不会有问题 不知道各位大侠有没有办法解决这个问题
