我有这样的XML结构:
<TR>
<Zeile status="done">
<Typ>FUNCTION</Typ>
<Name>PressKey</Name>
</Zeile>
<Zeile status="failed">
<Typ>FUNCTION</Typ>
<Name>PressKey</Name>
</Zeile>
<Zeile status="warn">
<Typ>FUNCTION</Typ>
<Name>PressKey</Name>
</Zeile>
<Zeile status="done">
<Typ>FUNCTION</Typ>
<Name>PressKey</Name>
</Zeile>
</TR>
现在我想要使用最差的status
来获取Element。
status
值从最佳到最差的顺序:
done
ignoreFailed
ignoreExpected
passed
unknown
warn
failed
我该如何处理?最后,我希望在名为status
的变量中将最差的worst_status
作为整数,并在变量worst_status_string
这是我尝试的(但由于禁止覆盖变量而失败):
<xsl:variable name="statusMapping">
<statusMap>
<status key="done" value="1"/>
<status key="ignoreFailed" value="2"/>
<status key="ignoreExpected" value="3"/>
<status key="passed" value="4"/>
<status key="unknown" value="5"/>
<status key="warn" value="6"/>
<status key="failed" value="7"/>
</statusMap>
</xsl:variable>
<xsl:template match="//TR">
<xsl:variable name="worst_status" select="1"/>
<xsl:for-each select="Zeile">
<xsl:variable name="current_status" select="@status"/>
<xsl:for-each select="exslt:node-set($statusMapping)/statusMap/status">
<xsl:if test="@key = $current_status">
<xsl:if test="@value > $worst_status">
<xsl:variable name="worst_status" select="@value"/>
</xsl:if>
</xsl:if>
</xsl:for-each>
WorstStatus: <xsl:value-of select="$worst_status"/>
</xsl:for-each>
</xsl:template>
答案 0 :(得分:2)
按降序排序并取第一个:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
xmlns:exsl="http://exslt.org/common"
exclude-result-prefixes="exsl">
<xsl:variable name="statusMapping-rtf">
<status key="done" value="1"/>
<status key="ignoreFailed" value="2"/>
<status key="ignoreExpected" value="3"/>
<status key="passed" value="4"/>
<status key="unknown" value="5"/>
<status key="warn" value="6"/>
<status key="failed" value="7"/>
</xsl:variable>
<xsl:variable name="statusMapping" select="exsl:node-set($statusMapping-rtf)"/>
<xsl:template match="TR">
<xsl:variable name="worst_status">
<xsl:for-each select="Zeile">
<xsl:sort select="$statusMapping/status[@key = current()/@status]/@value" data-type="number" order="descending"/>
<xsl:if test="position() = 1">
<xsl:value-of select="$statusMapping/status[@key = current()/@status]/@value"/>
</xsl:if>
</xsl:for-each>
</xsl:variable>
<xsl:variable name="worst_status_string" select="$statusMapping/status[@value = $worst_status]/@key"/>
<xsl:value-of select="concat($worst_status_string, ': ', $worst_status)"/>
</xsl:template>
</xsl:transform>
如果您确实需要将一个变量作为数字值,请添加<xsl:variable name="worst_status_number" select="number($worst_status)"/>
。
