Question

字符串长度约为120

这里是我的消息字符串： CID_Ultimate_Ben_Details = pabbisettishanmukhpraveenkumarpabbisettishanmukhpraveenkumarpabbisettishanmukhpraveenkumarpabbisettishanmukhpraveenkumar

例如：消息长度为140

输出所需的输出为：

1 to 35 chars in first line
36 t0 70 chars in second line
71 to 105 chars in third line
106 to 140 in fourth line

这是我的xslt逻辑：

<xsl:if test ="./CID_Ultimate_Ben_Details != '' " >
                <xsl:if test ="string-length(./CID_Ultimate_Ben_Details) != '11' and string-length(./CID_Ultimate_Ben_Details) != '8' ">
                    <xsl:if test="string-length(./CID_Ultimate_Ben_Details) &gt; 1">
                        <xsl:value-of select="concat(':58D:',substring(./CID_Ultimate_Ben_Details,1,35))" />
                    </xsl:if>
                    <xsl:if test="string-length(./CID_Ultimate_Ben_Details) &gt; 35">
                        <xsl:value-of select="concat('&#10;',substring(./CID_Ultimate_Ben_Details,36,70))" />
                    </xsl:if>
                    <xsl:if test="string-length(./CID_Ultimate_Ben_Details) &gt; 70">
                        <xsl:value-of select="concat('&#10;',substring(./CID_Ultimate_Ben_Details,71,105))" />
                    </xsl:if>
                    <xsl:if test="string-length(./CID_Ultimate_Ben_Details) &gt; 105">
                        <xsl:value-of select="concat('&#10;',substring(./CID_Ultimate_Ben_Details,106,140))" />
                    </xsl:if>
                </xsl:if>

                <xsl:text>&#13;</xsl:text >
            </xsl:if>

输出要求为：的：58D：pabbisettishanmukhpraveenkumarpabbi settishanmukhpraveenkumarpabbisetti shanmukhpraveenkumarpabbisettishanm ukhpraveenkumar

但是现在对于上面的逻辑输出就是这样：

：58D：pabbisettishanmukhpraveenkumarpabbi settishanmukhpraveenkumarpabbisettishanmukhpraveenkumarpabbisettishanm shanmukhpraveenkumarpabbisettishanmukhpraveenkumar ukhpraveenkumar

为什么它以无关的方式产生clrf。任何人都建议我取得我所需的输出

Answer 1

这是一个正确的和通用的（适用于任何文本长度和数量的输出行）XSLT 1.0解决方案（XSLT 2.0解决方案非常简单）：

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="text"/>
 <xsl:strip-space elements="*"/>

 <xsl:param name="pmsgLength" select="140"/>
 <xsl:param name="pnumLines" select="4"/>

 <xsl:variable name="vmaxLineLength" select=
  "ceiling($pmsgLength div $pnumLines)"/>

 <xsl:template match="/*/text()" name="split">
  <xsl:param name="pText" select="."/>
  <xsl:param name="pnextLines" select="$pnumLines"/>
  <xsl:param name="pHead" select="':58D:'"/>

    <xsl:if test="$pnextLines">
     <xsl:value-of select=
      "concat('&#xA;',$pHead, substring($pText, 1, $vmaxLineLength))"/>

      <xsl:call-template name="split">
       <xsl:with-param name="pText" select="substring($pText, $vmaxLineLength+1)"/>
       <xsl:with-param name="pnextLines" select="$pnextLines -1"/>
       <xsl:with-param name="pHead" select="''"/>
      </xsl:call-template>
    </xsl:if>
 </xsl:template>
</xsl:stylesheet>

将此转换应用于以下XML文档：

<t>pabbisettishanmukhpraveenkumarpabbisettishanmukhpraveenkumarpabbisettishanmukhpraveenkumarpabbisettishanmukhpraveenkumar</t>

生成所需的正确输出：

:58D:pabbisettishanmukhpraveenkumarpabbi
settishanmukhpraveenkumarpabbisetti
shanmukhpraveenkumarpabbisettishanm
ukhpraveenkumar

Answer 2

substring()的第三个参数是所需的长度，而不是Java中的结束位置。

以无关的方式产生clrf
