谁能帮我获取始终位于客户编号之前的邮政编码的值?
Can anyone help me to take always the value of the postcode which will be always before Customer No.?
<xsl:value-of select="substring-before(substring-after(substring-after(substring-after(Address,' '),' '),' '),' ')"/>
我已经使用了上面的但不打算在第二个例子中工作.需要找到一种方法来接下最后一个.
I have used the above but is not going to work on the second example. Need to find a way to take next to the last.
注意:每行之间有换行符(CRLF).
Note: there is Line breaks (CRLF) between each line.
非常感谢任何帮助
推荐答案
一种可能的方法是创建一个递归的substring-after-last"命名模板,并使用它传入出现在Customer No."之前的子字符串.
One possible way is to create a recursive "substring-after-last" named template, and use that passing in the substring that occurs before "Customer No. "
试试这个 XSLT
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text" indent="yes" />
<xsl:template match="Address">
<xsl:call-template name="substring-after-last">
<xsl:with-param name="text" select="$exCust" />
<xsl:with-param name="arg" select="' '" />
</xsl:call-template>
</xsl:template>
<xsl:template name="substring-after-last">
<xsl:param name="text" />
<xsl:param name="arg" />
<xsl:variable name="after" select="substring-after($text, $arg)" />
<xsl:choose>
<xsl:when test="contains($after, $arg)">
<xsl:call-template name="substring-after-last">
<xsl:with-param name="text" select="$after" />
<xsl:with-param name="arg" select="$arg" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$after" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
如果您只处理长度为 6 到 8 个字符(包括空格)的英国邮政编码,您可以通过一种非常粗略的方法来处理....
If you are only dealing with UK postcodes, which vary between 6 and 8 characters in length (including a space), you could do it via a very crude method....
<xsl:variable name="exCust" select="substring-before(., ' Customer No. ')" />
<xsl:value-of select="substring-after(substring($exCust, string-length($exCust) - 8, 9), ' ')" />
这有点小技巧,如果前面的城镇/城市的长度是一个字符,也会失败!
This is a bit of a hack though, and will also fail if the preceding town/city is one character in length!
