如何使用XSL从XML中的同一变量获取不同的值

Question

XML:

<message code="100" description="checkSnr">
  <string name="id"/>
  <string name="serialNr"/>
</message>

XSL:

<xsl:template match="/">
  <xsl:for-each select="machine/events"> 
    <xsl:text>;</xsl:text>
    <xsl:value-of select="message/@code"/>
    <xsl:text>;</xsl:text>
    <xsl:value-of select="message/string/@name"  />
    <xsl:text>;</xsl:text>
    <xsl:value-of select="message/string/@name"  />
  </xsl:for-each>
</xsl:template>

So here's my Problem. My XSL-File is supposed to detect the value "id" and the value "serialNr", but my Output is "id" x2. I know it is only Logical but how can I actually Change my XSL so it gives me both of the values? (by the way, in the XML there are parts, where the variable "string Name" is used like 4 times) I thought of rewriting the XML with a Loop so that the Name variables get renamed into name1, name2, name3 and so on, but I can't figure out how to do that. I use Java as a converter if you can think of any Solutions in Java. My Output Format is .CSV if that matters.

(any other tips on improving the XSL are appreciated aswell)

Thanks!

Answer 1

It is strange that you have 2 empty string tags.

I suppose, your XML should have the following shape:

<message code="100" description="checkSnr">
  <string name="id">1234</string>
  <string name="serialNr">5678</string>
</message>

Then you shoud read both string tags using name attribute with particular value as a predicate :

<xsl:template match="/">
  <xsl:for-each select="machine/events"> 
    <xsl:text>;</xsl:text>
    <xsl:value-of select="message/@code"/>
    <xsl:text>;</xsl:text>
    <xsl:value-of select="message/string[@name='id']"  />
    <xsl:text>;</xsl:text>
    <xsl:value-of select="message/string[@name='serialNr']"  />
  </xsl:for-each>
</xsl:template>
