如何使用xslt 1.0

时间：2015-07-12 05:51:52

标签： xml xslt-1.0

我有一个文本文件，条目由回车符和换行符分隔。每个树编号的一个条目以及相应的标题和标题通过分号与树编号分开。

文件中的示例文字 

Body Regions;A01
Anatomic Landmarks;A01.111
Breast;A01.236
Mammary Glands, Human;A01.236.249
Nipples;A01.236.500
Extremities;A01.378
Amputation Stumps;A01.378.100
Lower Extremity;A01.378.610
Buttocks;A01.378.610.100
Foot;A01.378.610.250
Ankle;A01.378.610.250.149
Forefoot, Human;A01.378.610.250.300
Metatarsus;A01.378.610.250.300.480

从上面的例子中： 树编号为Thumb的{​​{1}}属于A01.378.800.667.430.705的一部分，Fingers;A01.378.800.667.430属于Hand;A01.378.800.667的一部分，Upper Extremity;A01.378.800属于Extremities;A01.378的一部分root是Body Regions;A01。

如果可以假设每个＆＃34;步骤＆＃34;在id中只有3个字符长，那么你可以这样做：

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:key name="child" match="ROW" use="substring(id, 1, string-length(id) - 4)" />

<xsl:template match="/ROWSET">
    <node id="MESH" label="NIH Medical Subject Headings">
        <xsl:apply-templates select="ROW[not(contains(id, '.'))]"/>
    </node>
</xsl:template>

<xsl:template match="ROW">
    <node id="{id}" label="{label}">
        <xsl:variable name="children" select="key('child', id)" />
        <xsl:if test="$children">
            <isComposedBy>
                <xsl:apply-templates select="$children"/>
            </isComposedBy>
        </xsl:if>
    </node>
</xsl:template>

</xsl:stylesheet>

否则它变得更复杂（在XSLT 1.0中）并且使用EXSLT扩展在这里将非常有用 - 如果您的处理器可以支持它。

或者，因为您的输入似乎来自数据库，如果您可以将其输出修改为：

<ROWSET>
    <ROW>
        <label>Body Regions</label>
        <id>A01</id>
        <parent-id/>
    </ROW>
    <ROW>
        <label>Anatomic Landmarks</label>
        <id>A01.111</id>
        <parent-id>A01</parent-id>
    </ROW>
    <ROW>
        <label>Breast</label>
        <id>A01.236</id>
        <parent-id>A01</parent-id>
    </ROW>
    <ROW>
        <label>Mammary Glands, Human</label>
        <id>A01.236.249</id>
        <parent-id>A01.236</parent-id>
    </ROW>
    ...
    <ROW>
        <label>Shoulder</label>
        <id>A01.378.800.750</id>
        <parent-id>A01.378.800</parent-id>
    </ROW>
</ROWSET>

你会有一个更方便的起点。
