修改项目大于或小于整数的节点项目？

Question

我需要 output/amend 项 XML 其中一项

<TrackNumber> 匹配数字 2 之后（到无穷大）整数值
从 XML 读取的值大于、小于、小于或等于指定的整数值

条件：对于从 TrackNumber 2 开始（到无穷大）匹配的项目：

FOR <ScannedTrack>
WHERE <TrackNumber>2 (and onwards)
IF <Codec>2048</Codec>
AND <Bitrate> is <= LESS THAN OR EQUAL TO <Bitrate>192000</Bitrate>

OUTPUT/WRITE <Encoder> item as:
<Encoder>Ac3Passthrough</Encoder>
AND DELETE element/node <MixDown>


FOR <ScannedTrack>
<TrackNumber>2 (and onwards)
IF <Codec>2048</Codec> or <Codec>16777216</Codec> or <Codec>262144</Codec> or <Codec>8192</Codec> or <Codec>4444</Codec>
AND <Bitrate> is > GREATER THAN <Bitrate>192000</Bitrate>

OUTPUT/WRITE the following to each specific item:
<AudioTrack>
<MixDown>stereo</MixDown>
<Encoder>Ac3</Encoder>
<Bitrate>192</Bitrate>

注意： 元素 <MixDown>, <Encoder> and <Bitrate> 已经包含现有值，因此 replace/overwrite 这些元素与上面显示的 output/write 值匹配条件。

有人可以帮助我编写脚本 - VBScript、XSLT 或 Batch with Regex 以帮助实现所需的输出吗？

我尝试使用下面的 XSL 样式表代码，但我认为我的一些语法不正确，需要一些帮助：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

        <xsl:mode on-no-match="shallow-copy"/>

        <xsl:template match="AudioTrack[ScannedTrack/TrackNumber = (>= '2')]">
            <xsl:template match="AudioTrack[ScannedTrack[Codec = (2048)] and [Bitrate (<=192000)]/Encoder">
                <xsl:copy>Ac3Passthrough</xsl:copy>
            </xsl:template>


            <xsl:template match="AudioTrack[ScannedTrack/TrackNumber = (>= '2')]">
                <xsl:template match="AudioTrack[ScannedTrack[Codec = (2048, 262144, 8192, 4444, 16777216)] and [Bitrate = (>192000)]/MixDown/Encoder/Bitrate">
                    <xsl:copy>Stereo</xsl:copy>
                    <xsl:copy>Ac3</xsl:copy>
                    <xsl:copy>192</xsl:copy>
                </xsl:template>

            </xsl:stylesheet>

这是要测试的示例 XML 文件：

这很难，time-consuming 很难理解。 AFAICT，您想做的事：

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<!-- identity transform -->
<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="AudioTrack[ScannedTrack/TrackNumber > 1 and ScannedTrack/Codec = 2048 and ScannedTrack/Bitrate &lt;= 192000]">
    <xsl:copy>
        <Encoder>Ac3Passthrough</Encoder>
        <xsl:apply-templates select="*[not(self::MixDown or self::Encoder)]"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="AudioTrack[ScannedTrack/TrackNumber > 1 and (ScannedTrack/Codec = 2048 or ScannedTrack/Codec = 262144 or ScannedTrack/Codec = 8192 or ScannedTrack/Codec = 4444) and ScannedTrack/Bitrate > 192000]">
    <xsl:copy>
        <MixDown>stereo</MixDown>
        <Encoder>Ac3</Encoder>
        <Bitrate>192</Bitrate>
        <xsl:apply-templates select="*[not(self::MixDown or self::Encoder or self::Bitrate)]"/>
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>

为回复您的评论而添加：

如果要保留 AudioTrack 下元素的原始顺序，请尝试：

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<!-- identity transform -->
<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="AudioTrack[ScannedTrack/TrackNumber > 1 and ScannedTrack/Codec = 2048 and ScannedTrack/Bitrate &lt;= 192000]">
    <xsl:copy>
        <xsl:apply-templates select="IsNotifying | DRC | Gain"/>        
        <Encoder>Ac3Passthrough</Encoder>
        <xsl:apply-templates select="SampleRate | EncoderRateType | Bitrate | Quality | TrackName | IsDefault | SampleRateDisplayValue | ScannedTrack"/>
    </xsl:copy>
</xsl:template>
