我有一个这样的xml表:
<tr>
<td><font face="Calibri">Tank CIP warning interval (Hours)</font></td>
<td><font face="Calibri">||MIN_CIP_EXPIRE_TIME||</font></td>
<td><font face="Calibri">CIP Check - Tank Filter</font></td>
<td><font face="Calibri">Equipment</font></td>
<td><font face="Calibri">True</font></td>
</tr>
<tr>
<td><font face="Calibri">Vent Filter Material ID</font></td>
<td><font face="Calibri">||MM_EXPECTED_FILTER_MATL_ID_01||</font></td>
<td><font face="Calibri">Scan/Install/Consume Vent Filters</font></td>
<td><font face="Calibri">Materials</font></td>
<td><font face="Calibri">False</font></td>
</tr>
我必须通过比较TagName,用以下xml字符串中的“ Step Reference”替换整个xml中的第3个元素文本。
<Data>
<row>
<BoPName>OP_R_CFG_DEFINED_WEIGH_SEQUENCE</BoPName>
<TagName>||MIN_CIP_EXPIRE_TIME||</TagName>
<StepReference>Calculate Expiry</StepReference>
</row>
<row>
<BoPName>OP_R_CFG_FIRST_ADD_EXP_INTERVAL</BoPName>
<TagName>||MM_EXPECTED_FILTER_MATL_ID_01||</TagName>
<StepReference>Scan Material</StepReference>
</row>
<Data>
CIP检查-储罐过滤器必须替换为计算到期时间。
答案 0 :(得分:1)
假设您不希望xslt 1.0是2.0,那么类似
<table>
<tr>
<td><font face="Calibri">Tank CIP warning interval (Hours)</font></td>
<td><font face="Calibri">||MIN_CIP_EXPIRE_TIME||</font></td>
<td><font face="Calibri">CIP Check - Tank Filter</font></td>
<td><font face="Calibri">Equipment</font></td>
<td><font face="Calibri">True</font></td>
</tr>
<tr>
<td><font face="Calibri">Vent Filter Material ID</font></td>
<td><font face="Calibri">||MM_EXPECTED_FILTER_MATL_ID_01||</font></td>
<td><font face="Calibri">Scan/Install/Consume Vent Filters</font></td>
<td><font face="Calibri">Materials</font></td>
<td><font face="Calibri">False</font></td>
</tr>
</table>
带有数据文件tab2.xml
<Data>
<row>
<BoPName>OP_R_CFG_DEFINED_WEIGH_SEQUENCE</BoPName>
<TagName>||MIN_CIP_EXPIRE_TIME||</TagName>
<StepReference>Calculate Expiry</StepReference>
</row>
<row>
<BoPName>OP_R_CFG_FIRST_ADD_EXP_INTERVAL</BoPName>
<TagName>||MM_EXPECTED_FILTER_MATL_ID_01||</TagName>
<StepReference>Scan Material</StepReference>
</row>
</Data>
您可以构建键查找,例如
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:variable name="data" select="document('tab2.xml')"/>
<xsl:key name="k" match="StepReference" use="../TagName"/>
<xsl:template match="node()">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="td/font/text()">
<xsl:variable name="here" select="."/>
<xsl:variable name="tn" select="../../preceding-sibling::*[1]/font"/>
<xsl:for-each select="$data">
<xsl:choose>
<xsl:when test="key('k',$tn)">
<xsl:value-of select="key('k',$tn)"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$here"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
制作:
$ xsltproc tab.xsl tab.xml
<?xml version="1.0"?>
<table>
