我有一个巨大的字符串进入XSLT（1.0），我必须把这个字符串分成一定数量的字符串（这是一个静态数字）具有一定的长度（这也是一个静态数字），但我不应该让词被切断。例如：我有以下字符串
这是为了在打印应用程序PDF时测试单词剪切产品。
长度为35的String1应为： 这是为了测试单词cut
带有35的String2应该是： 提供印刷
String3剩余全部： 申请PDF。
还请建议如何在XSLT2.0中进行操作。
答案 0 :(得分：2)
这是一个简单的解决方案，使用FXSL library 中的str-split-to-lines模板：
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:f="http://fxsl.sf.net/"
xmlns:ext="http://exslt.org/common"
xmlns:str-split2lines-func="f:str-split2lines-func"
exclude-result-prefixes="xsl f ext str-split2lines-func"
>
<xsl:import href="dvc-str-foldl.xsl"/>
<!-- to be applied on text.xml -->
<str-split2lines-func:str-split2lines-func/>
<xsl:output indent="yes" omit-xml-declaration="yes"/>
<xsl:template match="/">
<xsl:call-template name="str-split-to-lines">
<xsl:with-param name="pStr" select="/*"/>
<xsl:with-param name="pLineLength" select="64"/>
<xsl:with-param name="pDelimiters" select="' 	 '"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="str-split-to-lines">
<xsl:param name="pStr"/>
<xsl:param name="pLineLength" select="60"/>

</xsl:for-each>
<xsl:value-of select="'

</xsl:for-each>
</xsl:template>
<xsl:template match="str-split2lines-func:*" mode="f:FXSL">
<xsl:param name="arg1" select="/.."/>
<xsl:param name="arg2"/>
<xsl:copy-of select="$arg1/*[position() < 3]"/>

</xsl:call-template>
</xsl:if>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="$arg1/line[last()]"/>
<word><xsl:value-of select="concat($arg1/word, $arg2)"/></word>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<!-- Test if the new word fits into the last line -->
<xsl:template name="fillLine">
<xsl:param name="pLine" select="/.."/>
<xsl:param name="pWord" select="/.."/>
<xsl:param name="pLineLength" />
<xsl:variable name="vnWordsInLine" select="count($pLine/word)"/>
<xsl:variable name="vLineLength"
select="string-length($pLine) + $vnWordsInLine"/>
<xsl:choose>
<xsl:when test="not($vLineLength + string-length($pWord)

<xsl:copy-of select="$pLine/*"/>
<xsl:copy-of select="$pWord"/>
</line>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="$pLine"/>
<line>
<xsl:copy-of select="$pWord"/>
</line>
<word/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
将此转换应用于以下XML文档：
<text>
Dec. 13 — As always for a presidential inaugural, security and surveillance were
extremely tight in Washington, DC, last January. But as George W. Bush prepared to
take the oath of office, security planners installed an extra layer of protection: a
prototype software system to detect a biological attack. The U.S. Department of
Defense, together with regional health and emergency-planning agencies, distributed
a special patient-query sheet to military clinics, civilian hospitals and even aid
stations along the parade route and at the inaugural balls. Software quickly
analyzed complaints of seven key symptoms — from rashes to sore throats — for
patterns that might indicate the early stages of a bio-attack. There was a brief
scare: the system noticed a surge in flulike symptoms at military clinics.
Thankfully, tests confirmed it was just that — the flu.

生成所需的正确结果（文本被分成不超过64个字符的行，并且两行之间没有单词分开）：

请注意：
转换通常会导入包含str-split-to-lines的xslt文件，因此代码会更短。
为完整起见，这是唯一导入的XSLT样式表：
