XSLT: A simple way to merge xml files
提问by nicholas.alipaz
I have two xml files. I need to merge them together where the element "myid" matches between the two. Please have a look at these example files...
我有两个 xml 文件。我需要将它们合并在一起，其中元素“myid”在两者之间匹配。请看一下这些示例文件...
File1.xml:
文件1.xml：
<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
<data>
<title>Title1</title>
<description>Description1</description>
<myid>1</myid>
</data>
<data>
<title>Title2</title>
<description>Description2</description>
<myid>2</myid>
</data>
</catalog>
File2.xml:
文件2.xml：
<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
<data>
<author>Author1</author>
<date>12/34/5678</date>
<myid>1</myid>
</data>
<data>
<author>Author2</author>
<date>87/65/4321</date>
<myid>2</myid>
</data>
</catalog>
The resulting file would look like:
生成的文件如下所示：
<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
<data>
<title>Title1</title>
<description>Description1</description>
<myid>1</myid>
<author>Author1</author>
<date>12/34/5678</date>
</data>
<data>
<title>Title2</title>
<description>Description2</description>
<myid>2</myid>
<author>Author2</author>
<date>87/65/4321</date>
</data>
</catalog>

I have been researching a bit and found a fairly similar question here: http://forums.tizag.com/showthread.php?p=76699
我一直在研究，在这里发现了一个相当相似的问题：http: //forums.tizag.com/showthread.php?p=76699
Here is what I have come up with, this seems to be mostly working except that Firefox is not recognizing it as an xml file even though I have added the xml:output.
这是我想出的，这似乎主要是有效的，除了 Firefox 没有将其识别为 xml 文件，即使我添加了 xml:output。
File1.xml (note line two, referencing our transformation):
File1.xml（注意第二行，引用我们的转换）：
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="merge.xsl"?>
<catalog>
<data>
<title>Title1</title>
<description>Description1</description>
<myid>1</myid>
</data>
<data>
<title>Title2</title>
<description>Description2</description>
<myid>2</myid>
</data>
</catalog>
File2.xml:
文件2.xml：
<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
<data>
<author>Author1</author>
<date>12/34/5678</date>
<myid>1</myid>
</data>
<data>
<author>Author2</author>
<date>87/65/4321</date>
<myid>2</myid>
</data>
</catalog>
merge.xsl:
合并.xsl：
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="ISO-8859-1" indent="yes" />
<xsl:variable name="with" select="'File2.xml'" />
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="scene">
<xsl:copy>
<xsl:apply-templates select="@*|node()" />
<xsl:variable name="info" select="document($with)/catalog/data[myid=current()/myid]/." />
<xsl:for-each select="$info/*">
<xsl:if test="name()!='myid'">
<xsl:copy-of select="." />
</xsl:if>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:transform>
Output xml when viewing File1.xml:
查看File1.xml时输出xml：
<catalog>
<data>
<title>Title1</title>
<description>Description1</description>
<myid>1</myid>
<author>Author1</author>
<date>12/34/5678</date>
</data>
<data>
<title>Title2</title>
<description>Description2</description>
<myid>2</myid>
<author>Author2</author>
<date>87/65/4321</date>
</data>
</catalog>
