Thanks, please see my code:

xanada(㊣流水)

以下是我的xml:
<entry>111</entry>
<entry b="1">222</entry>
<entry href="google">333</entry>
<entry href="yahoo" b="1">444</entry>
<entry></entry>

要显示在html的table里面：
111 -> 正常
222 -> 黑体222
333 -> 链接<a href="google">333</a>
444 -> 黑体并链接<a href="yahoo">333</a>
最后一项显示"NA"

<xsl:template match="entry">
<xsl:variable name="link" select="@href" />
<xsl:variable name="b" select="@b" />

<xsl:choose>
<xsl:when test='boolean($link)'>
<a href="{$link}"><xsl:value-of select="."/></a>
</xsl:when>

<xsl:otherwise>
<xsl:value-of select="."/>
</xsl:otherwise>
</xsl:choose>

</xsl:template>

接下来该怎么写呢？我试图在when里面再用if来判断，可是不行。请指点。（如果可以，请把code贴出来，这样就省了一大堆解释的话了。）

好象choose-when-otherwise里面不能再嵌套if之类的语句了。

请各位高手牛人给个提示，谢谢。

you can use several "when"s and you may also need use more filter operators as well in your boolean expression. -yuanzidan(原子弹); 2003-1-24 (#997097@0)

when不能嵌套？我比较蠢，能否给点详细提示？ -xanada(㊣流水); 2003-1-24 (#997102@0)

我其实也想帮你想来着, 因为 1.今天挺忙 2.XSLT确实别扭 3.看你总夸别人是好同志所以我就没管你... :-P -decentboy(曾经的帝国骑士); 2003-1-24 (#997619@0)

谢谢你还替我惦记着呢 :-) 最近比较颓废, 去年借口说到今年再考, 现在想过了春节再说, 后来发现还有情人节, 某些纪念日什么的....还是等冬天没什么事儿的时候再说吧.. :-P -decentboy(曾经的帝国骑士); 2003-1-24 (#997636@0)

You are really great! At last i worked it out, and here's my "very very un-professional" code (i'm also new to it, hehe) for your reference.

<xsl:template match="entry">

<xsl:variable name="link" select="@href" />
<xsl:variable name="b" select="@b" />

<xsl:choose>
<xsl:when test='boolean($link)'>
<a href="{$link}">

<xsl:choose>
<xsl:when test='boolean($b)'>
<xsl:value-of select="."/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="."/>
</xsl:otherwise>
</xsl:choose>

</a>
</xsl:when>

<xsl:otherwise>

<xsl:choose>
<xsl:when test='boolean($b)'>
<xsl:value-of select="."/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="."/>
</xsl:otherwise>
</xsl:choose>

</xsl:otherwise>
</xsl:choose>

</xsl:template>
