某些条件下的 Xslt [英] Xslt under some conditions

问题描述

我是 xml 和 xslt 的新手.我有一些以某些值的形式存在的数据.

I am new to xml and xslt. I have some data which is in the form of some values.

假设这是一个 xml

<root>
    <z>517-98-0045</z>
    <z1>449-235-1235</z1>
    <z2>4265-6857-1293-0098</z2>
    <z3>3232-3-3232-3232-12</z3>
    <z4>449-235-1235</z4>
    <z5>332323-32-322</z5>
    <z6>218-28-2332</z6>
    <z7>517-98-0045</z7>
</root>

应该改为如下:

<z>517-xx-xxxx</z>
<z1>449-xxx-xxxx</z1>
<z2>4265-xxxx-xxxx-xxxx</z2>
<z3>3232-3-3232-3232-12</z3>
<z4>449-xxx-xxxx</z4>
<z5>332323-32-322</z5>
<z6>218-28-2332</z6>
<z7>517-xx-xxxx</z7>

所以这意味着每当 xslt 遇到三个值

So this means whenever xslt comes accross the three values

517-98-0045
449-235-1235
4265-6857-1293-0098

它必须把它变成这个

517-XX-XXXX
449-XXX-XXXX
4265-XXXX-XXXX-XXXX

我知道正则表达式可以做到这一点，但我该怎么做呢?

I know that regular expressions can accomplish this, but how can I do that?

根据下面给出的答案..以下是否正确---

According to the undergiven answers..Is this following correct---

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
  <xsl:template match="/">
<xsl:when test="matches(517-98-0045,'\d{3}-\d{2}-\d{4}')">
    <xsl:value-of select="replace('517-98-0045','517-XX-XXXX');"/>
  </xsl:when>
<xsl:when test="matches(449-235-1235,'\d{3}-\d{3}-\d{4}')">
    <xsl:value-of select="replace('449-235-1235','449-XX-XXXX');"/>
  </xsl:when>
<xsl:when test="matches(4265-6857-1293-0098,'\d{4}-\d{4}-\d{4}-\d{4}')">
    <xsl:value-of select="replace('4265-6857-1293-0098','4265-XXxx-XXXX-xxxx');"/>
  </xsl:when>
<xsl:template>
<xsl:stylesheet>

推荐答案

如果您只想替换这三个特定值，那么应该这样做:

If you just want to replace those three particular values, then this should do it:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes"/>

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="text()[. = '517-98-0045' or
                              . = '449-235-1235' or
                              . = '4265-6857-1293-0098']">
    <xsl:value-of select="concat(substring-before(., '-'), 
                                 '-',
                                 translate(substring-after(., '-'),
                                           '0123456789', 'XXXXXXXXXX'))"/>
  </xsl:template>
</xsl:stylesheet>
