<body>
<salutation>Dear Mother,</salutation>
<p><line>This is the first letter I have had</line>
<line>an opportunity to write you since leaving Fort</line>
<line>Jay, and I know you must be anxious to hear from me.</line></p>
<p><line>Bob and I are both feeling as well as</line>
<line>can be expected considering our present cir-</line>
<line>cumstances. We both have high blood</line>
<line>pressure, mine has been 160/100 for the past</line>
<line>2 days, and Bob's 158/96, but my sinus</line>
<line>infection has not caused me quite so much</line>
<line>trouble since leaving N.Y. State. I believe</line>
<line>the air is dryer here and is responsible</line>
<line>for any alleviation that has taken place.</line></p>
<p><line>While a prisoner here remains in their</line>
<line>so-called 1st grade, he is able to write</line>
<line>twice a week, in second grade once a week,</line>
<line>and in third grade once a month. These</line>
<line>grades refer to classifications that ostensibly</line>
<line>are for conduct while here. It is quite possible</line>
<line>to lose a conduct rating, as I understand it,</line>
<line>by not having a perpetually rusting tin cup polished</line>
<pb n="2"/>
<line>brightly for daily inspection, although the tin plating long ago dis-</line>
<line>appeared and the cup is rusty again within 2 hours after wetting.</line></p>
<p><line>The food here is good and is well-cooked,</line>
<line>with one exception, the gravy, which is nothing but</line>
<line>flour, water, and bacon grease, Strangely enough, how-</line>
<line>ever, no condiments, not even salt, are provided on</line>
<line>the table, to the detriment of otherwise very good</line>
<line>meals. While meat here is unrationed and is plentiful,</line>
<line>toilet paper; believe it or not, is rationed. A</line>
<line>5¢ roll must last a prisoner 45 days, or else -- ?</line>
<line>Perhaps, however, a prisoner can purchase additional</line>
<line>if it should be necessary.</line></p>
<p><line>Please see that my subscriptions are transferred</line>
<line>here as soon as possible from Fort Jay. Give Florence</line>
<line>and Helen my regards, and thank Joe for his</line>
<line>efforts in my behalf in managing my business.</line>
<line>Find out from Joe how tube deliveries are at the</line>
<line>present time, first to satisfy my curiosity; and</line>
<line>also let me know if you are receiving your</line>
<line>remittance regularly from him. If he is not</line>
<line>taking care of your support in accordance with</line>
<line>the instructions I left him, I wish to know it,</line>
<line>so I can write, and correct the matter.</line>
<line>You can tell Joe to subscribe to Electronics</line>
<line>magazine for me and send it to this address</line>
<line>direct from the publisher. He should also have a copy</line>
<line>of Palmer's "Calculus for Home Study," sent me by the publisher,</line>
<line>whose name he can obtain from Ulbrichs. In future letters I'll</line>
<line>copy the "Prisoner's Handbook" issued here, and the</line>
<line>contents of the detached letter form stub.</line>

我想转换 xml 以便仅显示图像及其说明。这是我的 xsl:
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<html>
<head>
<link rel="stylesheet" type="text/css" href="letter.css"/>
<title>Letter</title>
</head>
<body>
<div>
<xsl:apply-templates/>
</div>
</body>
</html>
</xsl:template>
<xsl:template match="//imageGroup">
<xsl:if test="//imageGroup">
<div class="image">
<xsl:for-each select="//imageGroup">
<img src="{image/@xlink:href}"/>
<span class="caption"><xsl:value-of select="caption"/></span>
</xsl:for-each>
</div>
</xsl:if>
</xsl:template>
问题是，我的输出仍然显示所有文本，而且我的图像加倍了。如何在不更改 xml?
中的任何内容的情况下修复它
将 <xsl:apply-templates/> 替换为 <xsl:apply-templates select="//imageGroup"/>，那么您的这些元素的模板当然不应该使用任何 for-each，而是简单地显示每个图像，例如
<xsl:template match="imageGroup">
<img src="{image/@xlink:href}"/>
<span class="caption"><xsl:value-of select="caption"/></span>
</xsl:template>
