XSL模糊规则混淆
XSL模糊规则混淆
提问于 2015-12-07 12:59:09
我收到一个模糊的规则匹配错误，正在抛出我。这是一个错误：
Recoverable error
XTRE0540: Ambiguous rule match for
/dmodule/content[1]/description[1]/levelledPara[2]/levelledPara[4]/table[1]
Matches both "table[parent::levelledPara] | table[parent::proceduralStep]" on line 3047 of
file:/c:/users/c79460/AppData/Local/PWC%20PDF%20Generator/test3.xsl
and "table[not(parent::levelledPara)] | table[not(parent::proceduralStep)]" on line 2962
of file:/c:/users/c79460/AppData/Local/PWC%20PDF%20Generator/test3.xsl我看不出根据所引用的两条规则和它所匹配的道路，哪里会有任何含糊不清的地方。在我看来，这个表有一个levelledPara父表，所以为什么我会得到不匹配规则的歧义(父表：：平面parent )？我相信我可能错过了一些可笑的简单的东西，希望一些新的视角会抓住它。这仅仅是因为我在match语句中使用了两个不同的父标记(levelledPara和proceduralStep)。

这是因为levelledPara/table与table[parent::levelledPara]和table[not(parent::proceduralStep)]都匹配。你可能打算写：
<xsl:template match="table[not(parent::levelledPara or parent::proceduralStep)]">而不是：
<xsl:template match="table[not(parent::levelledPara)] | table[not(parent::proceduralStep)]">这仅仅是因为我在match语句中使用了两个不同的父标记(levelledPara和proceduralStep)。
但你没有or。您有union接线员。你是在联合桌子而不是他们的父母。这也会奏效的：
<xsl:template match="table[not(parent::levelledPara | parent::proceduralStep)]">页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
