我有来自某些硬件的类似传入XML:
<invoice>
<field name="item">Item 1;Item 2;Item 3</field>
<field name="price">32.0;192.2;12.0</field>
<field name="quantity">1;4;2</field>
</invoice>
我需要转换类似于:
<invoice>
<item>
<desc>Item 1</desc>
<price>32.0</price>
<quantity>1</quantity>
</item>
<item>
<desc>Item 1</desc>
<price>192.0</price>
<quantity>4</quantity>
</item>
<item>
<desc>Item 3</desc>
<price>12.0</price>
<quantity>2</quantity>
</item>
</invoice>
目前我已经尝试过str:tokenize(),但主要问题是构建一个简单的循环。我对XSLT的了解非常基础,我的工作进展到目前为止:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0" xmlns:str="http://exslt.org/strings">
<xsl:output method="xml" indent="yes" version="1.0" encoding="UTF-8" omit-xml-declaration="yes" />
<xsl:template match="inovice">
<xsl:param name="separator" select="';'"/>
<xsl:param name="desc" select="str:tokenize(field[@name='item'],$separator)"/>
<xsl:param name="price" select="str:tokenize(field[@name='price'],$separator)"/>
<xsl:param name="quantity" select="str:tokenize(field[@name='quantity'],$separator)"/>
<xsl:param name="count" select="count($desc)"/>
<!-- some loop goes here -->
</xsl:template>
</xsl:stylesheet>
答案 0 :(得分:3)
一个简单的XSLT 2.0样式表,它迭代所有项目并根据当前位置选择相应的价格/数量,如下所示:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="invoice">
<xsl:variable name="fields" select="field"/>
<invoice>
<xsl:for-each select="tokenize(field[@name='item'], ';')">
<xsl:variable name="pos" select="position()"/>
<item>
<desc>
<xsl:value-of select="."/>
</desc>
<price>
<xsl:value-of select="tokenize($fields[@name='price'], ';')[position()=$pos]"/>
</price>
<quantity>
<xsl:value-of select="tokenize($fields[@name='quantity'], ';')[position()=$pos]"/>
</quantity>
</item>
</xsl:for-each>
</invoice>
</xsl:template>
</xsl:stylesheet>
如果要将XSLT 1.0与EXSLT扩展模块 strings 一起使用,则必须仅修改样式表:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:str="http://exslt.org/strings"
extension-element-prefixes="str">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="invoice">
<xsl:variable name="fields" select="field"/>
<invoice>
<xsl:for-each select="str:tokenize(field[@name='item'], ';')">
<xsl:variable name="pos" select="position()"/>
<item>
<desc>
<xsl:value-of select="."/>
</desc>
<price>
<xsl:value-of select="str:tokenize($fields[@name='price'], ';')[position()=$pos]"/>
</price>
<quantity>
<xsl:value-of select="str:tokenize($fields[@name='quantity'], ';')[position()=$pos]"/>
</quantity>
</item>
</xsl:for-each>
</invoice>
</xsl:template>
</xsl:stylesheet>
