将XML文件转换为CSV
问题描述:
在使用regex转换了一个混乱的XML之后,我现在需要再次更改它。
此源文件
After having converted a messed up XML using regex, I now need to change it yet again. This source file
<product>
<sku>SP00001</sku>
<PID_OWNER_SellerID>StoreName</PID_OWNER_SellerID>
<EANCode>8711983489813</EANCode>
<DeliveryDays>2</DeliveryDays>
</product>
必须成为CSV档案,但是像这样:
Has to become a CSV file, but like this:
sku field value
SP00001 PID_OWNER_SellerID StoreName
SP00001 EANCode 8711983489813
SP00001 DeliveryDays 2
我认为这是在regex的范围之外,必须使用XSL吗?
I take it this is outside of regex' scope and has to be done with XSL?
答
这里有一些XSLT ...
Here is some XSLT for you...
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
exclude-result-prefixes="msxsl"
>
<xsl:output method="text" indent="yes"/>
<xsl:template match="/">
<xsl:call-template name="headerRow" />
<xsl:apply-templates select="//product" />
</xsl:template>
<xsl:template name="headerRow">
<xsl:call-template name="rightpad">
<xsl:with-param name="fieldvalue" select="'sku'"/>
<xsl:with-param name="fieldsize" select="number(11)"/>
</xsl:call-template>
<xsl:call-template name="rightpad">
<xsl:with-param name="fieldvalue" select="'field'"/>
<xsl:with-param name="fieldsize" select="number(22)"/>
</xsl:call-template>
<xsl:text>value
</xsl:text>
</xsl:template>
<xsl:template match="product">
<xsl:for-each select="node()[local-name(.) != 'sku']">
<xsl:call-template name="rightpad">
<xsl:with-param name="fieldvalue" select="../sku"/>
<xsl:with-param name="fieldsize" select="number(11)"/>
</xsl:call-template>
<xsl:call-template name="rightpad">
<xsl:with-param name="fieldvalue" select="local-name(.)"/>
<xsl:with-param name="fieldsize" select="number(22)"/>
</xsl:call-template>
<xsl:value-of select="."/>
<xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:template>
<xsl:template name="rightpad">
<xsl:param name="fieldvalue" select="string('')"/>
<xsl:param name="fieldsize" select="0"/>
<xsl:variable name="padded"
select="concat($fieldvalue, ' ')" />
<xsl:variable name="result"
select="substring($padded,1,$fieldsize)" />
<xsl:value-of select="$result"/>
</xsl:template>
</xsl:stylesheet>
