我有以下文件要处理:
<root>
<html>
<table class=" table search-results-property-table">
<prefterm>Abies</prefterm>
<tr>
<td>
<span class="versal property-click" title="Broader concept">BROADER CONCEPT</span>
</td>
<td>
<ul>
<li>
<a class="versal" href="../../../agrovoc/en/page/c_5886">Pinaceae</a>
</li>
</ul>
</td>
</tr>
<tr>
<td>
<span class="versal property-click" title="Narrower concepts.">NARROWER CONCEPTS</span>
</td>
<td>
<ul>
<li>
<a class="versal" href="../../../agrovoc/en/page/c_11">Abies alba</a>
</li>
<li>
<a class="versal" href="../../../agrovoc/en/page/c_26316">Abies amabilis</a>
....
<li>
<a class="versal" href="../../../agrovoc/en/page/c_26323">Abies veitchii</a>
</li>
....
</table>
</html>
<html>
.... (another set to crosswalk)
</html>
</root>
使用下面的xslt，我可以得到只有一个值的更广泛的概念的值:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" omit-xml-declaration="yes" indent="no"/>
<xsl:template match="root">
<xsl:for-each select="html">
<xsl:text>START HERE</xsl:text>
<xsl:text> </xsl:text>
<xsl:text>=LDR 00000nam 2200000Ia 4500</xsl:text>
<xsl:text> </xsl:text>
</xsl:for-each>
</xsl:template>
<xsl:template match="table/tr/td/span">
<xsl:choose>
<xsl:when test="@title='Broader concept'">
<xsl:text>=301 \$a</xsl:text><xsl:value-of select="." />
<xsl:text>$b</xsl:text>
<xsl:value-of select="../../td/ul/li/a" />
<xsl:text>$c</xsl:text>
<xsl:value-of select="../../td/ul/li/a/@href" />
<xsl:text> </xsl:text>
</xsl:when>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
代码似乎与那些只有一个值的工作，我尝试添加xsl:for-each，但我不知道在哪里放，因为我是横向直到"a"。我尝试在第一个"xsl:choose"之前添加xsl:for-each select="//a"，并在xsl:when test="@title= "较窄的概念之后添加它。’"但无济于事。我希望输出如下所示:
START HERE
=LDR 00000nam 2200000Ia 4500
=301 \$abroaderterm$bPinaceae
=302 \$anarrowerterm$bAbies alba$cc_11
=302 \$anarrowerterm$bAbies amabilis$cc_26316
....
=302 \$anarrowerterm$bAbies veitchii$cc_26323
START HERE
=LDR 00000nam 2200000Ia 4500
(data set 2)
....
那么有人能告诉我应该做什么，或者我错过了什么，或者有其他方法来解决我的用例吗?谢谢大家，干杯!更新:请注意，我有不止一个人行横道，比如:
<root>
<html>
.... dataset 1
</html>
<html>
.... dataset 2
</html>
.... more than 2 datasets
</root>
作为参考，文件可以在这里找到:http://128.199.159.143/mergedhtmltest_forprocess_span.xml
给定格式良好的XML:
<root>
<html>
<table class=" table search-results-property-table">
<prefterm>Abies</prefterm>
<tr>
<td>
<span class="versal property-click" title="Broader concept">BROADER CONCEPT</span>
</td>
<td>
<ul>
<li>
<a class="versal" href="../../../agrovoc/en/page/c_5886">Pinaceae</a>
</li>
</ul>
</td>
</tr>
<tr>
<td>
<span class="versal property-click" title="Narrower concepts.">NARROWER CONCEPTS</span>
