本文介绍了XSLT 改进的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

这与 XSLT 可以进一步改进吗?有关.>

我有一个如下的 XML:

我有兴趣从上述两个可能的 xml 中获取 idref，以及相应的 title 和 result.

输出可能只是由 \n 分隔的纯文本.

我写的 XSL 如下:

但是，这并没有产生所需的输出?我在这里做错了什么?

请帮忙.

解决方案

您有几个问题:

  1. TestResult 不是根元素，所以你的模板:

    从不应用.您看到的输出纯粹是由内置模板规则.

  2. TestResult 没有 title 孩子，所以你的指令:

    不会返回任何东西.

  3. 当你这样做时:

    您已经处于 rule-result 的上下文中，因此您使用密钥是没有意义的.您忘记在 result 中包含 cdf: 前缀.

<小时>

根据您之前的问题，我认为您想查看 Group 下的 Rule 节点并获取链接的 rule-result从那里开始，而不是直接遍历 rule-result 节点:

XSLT 1.0

<xsl:output method="text" encoding="utf-8"/><xsl:key name="result" match="cdf:rule-result" use="@idref"/><xsl:template match="/cdf:Benchmark"><xsl:for-each select="cdf:Group/cdf:Rule"><xsl:value-of select="@id"/><xsl:text>&#xa;</xsl:text><xsl:value-of select="cdf:title"/><xsl:text>&#xa;</xsl:text><xsl:value-of select="key('result', @id)/cdf:result"/><xsl:text>&#xa;</xsl:text></xsl:for-each></xsl:模板></xsl:stylesheet>

应用于您的输入示例，结果将是:

xccdf_com.vmware.linux_rule_test-def-3规则 3 -/etc/passwd 文件归 root 所有经过xccdf_com.vmware.linux_rule_test-def-2规则 2 -/etc/passwd 文件归 root 所有经过xccdf_com.vmware.linux_rule_test-def-1规则 1 -/etc/passwd 文件的权限为 644 或更多限制经过

I have an XML as below:

I am interested in picking up idref, and corresponding title and resultfrom both the above possible xmls.

The out put could be just plain text separated by \n.

I wrote XSL as below:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:cdf="http://checklists.nist.gov/xccdf/1.2"
    xmlns:exsl="http://exslt.org/common"
    xmlns:db="http://docbook.org/ns/docbook"
    xmlns:xlink="http://www.w3.org/1999/xlink"
    xmlns="http://docbook.org/ns/docbook"
    xmlns:s="http://open-scap.org/"
    exclude-result-prefixes="xsl cdf db s exsl"
    xmlns:ovalres="http://oval.mitre.org/XMLSchema/oval-results-5"
    xmlns:sceres="http://open-scap.org/page/SCE_result_file"
    >

<xsl:output method="text" encoding="utf-8" />

<xsl:key name="result" match="cdf:rule-result" use="@idref" />

<xsl:template match="/cdf:TestResult">
    <xsl:for-each select="cdf:rule-result">
        <xsl:value-of select="@idref" />
        <xsl:text>&#xa;</xsl:text>
        <xsl:value-of select="cdf:title"/>
        <xsl:text>&#xa;</xsl:text>
        <xsl:value-of select="key('result', @idref)/result"/>
        <xsl:text>&#xa;</xsl:text>
    </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

But, this isn't generating the desired output? What am I doing wrong here?

Please help.

解决方案

You have several issues:

  1. TestResult is not the root element, so your template:

    <xsl:template match="/cdf:TestResult">

    is never applied. The output that you see is produced purely by the built-in template rules.

  2. TestResult has no title child, so your instruction:

    <xsl:value-of select="cdf:title"/>

    will not return anything.

  3. When you do:

    <xsl:for-each select="cdf:rule-result">

    you are already in the context of rule-result, so your use of a key makes no sense. And you forgot to include the cdf: prefix on the result.

Based on your previous question, I would think you want to go over the Rule nodes under Group and get the linked rule-result from there, instead of going over rule-result nodes directly:

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:cdf="http://checklists.nist.gov/xccdf/1.2">
<xsl:output method="text" encoding="utf-8" />

<xsl:key name="result" match="cdf:rule-result" use="@idref" />

<xsl:template match="/cdf:Benchmark">
    <xsl:for-each select="cdf:Group/cdf:Rule">
        <xsl:value-of select="@id" />
        <xsl:text>&#xa;</xsl:text>
        <xsl:value-of select="cdf:title"/>
        <xsl:text>&#xa;</xsl:text>
        <xsl:value-of select="key('result', @id)/cdf:result"/>
        <xsl:text>&#xa;</xsl:text>
    </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

Applied to your input example, the result will be:

xccdf_com.vmware.linux_rule_test-def-3
Rule 3 - /etc/passwd file is group-owned by root
pass
xccdf_com.vmware.linux_rule_test-def-2
Rule 2 - /etc/passwd file is owned by root
pass
xccdf_com.vmware.linux_rule_test-def-1
Rule 1 - /etc/passwd file has permissions of 644 or more restrictive
pass
