问题
I have a complex xml structure that looks like :
<Items>
<Item>
<ItemTexts>
<ItemText>
<ItemTextsType>type1</ItemTextsType>
<ItemTextsTypeDesc>description11</ItemTextsTypeDesc>
<ItemTextsLine>1</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type1</ItemTextsType>
<ItemTextsTypeDesc>description12</ItemTextsTypeDesc>
<ItemTextsLine>2</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type2</ItemTextsType>
<ItemTextsTypeDesc>description21</ItemTextsTypeDesc>
<ItemTextsLine>3</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type2</ItemTextsType>
<ItemTextsTypeDesc>description22</ItemTextsTypeDesc>
<ItemTextsLine>4</ItemTextsLine>
</ItemText>
</ItemTexts>
</Item>
<Item>
<ItemTexts>
<ItemText>
<ItemTextsType>type1</ItemTextsType>
<ItemTextsTypeDesc>description11</ItemTextsTypeDesc>
<ItemTextsLine>1</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type1</ItemTextsType>
<ItemTextsTypeDesc>description12</ItemTextsTypeDesc>
<ItemTextsLine>2</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type2</ItemTextsType>
<ItemTextsTypeDesc>description21</ItemTextsTypeDesc>
<ItemTextsLine>3</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type2</ItemTextsType>
<ItemTextsTypeDesc>description22</ItemTextsTypeDesc>
<ItemTextsLine>4</ItemTextsLine>
</ItemText>
</ItemTexts>
</Item>
<Item>
<ItemTexts>
<ItemText>
<ItemTextsType>type1</ItemTextsType>
<ItemTextsTypeDesc>description11</ItemTextsTypeDesc>
<ItemTextsLine>1</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type1</ItemTextsType>
<ItemTextsTypeDesc>description12</ItemTextsTypeDesc>
<ItemTextsLine>2</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type2</ItemTextsType>
<ItemTextsTypeDesc>description21</ItemTextsTypeDesc>
<ItemTextsLine>3</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type2</ItemTextsType>
<ItemTextsTypeDesc>description22</ItemTextsTypeDesc>
<ItemTextsLine>4</ItemTextsLine>
</ItemText>
</ItemTexts>
</Item>
<Item>
<ItemTexts>
<ItemText>
<ItemTextsType>type3</ItemTextsType>
<ItemTextsTypeDesc>description31</ItemTextsTypeDesc>
<ItemTextsLine>1</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type3</ItemTextsType>
<ItemTextsTypeDesc>description32</ItemTextsTypeDesc>
<ItemTextsLine>2</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type2</ItemTextsType>
<ItemTextsTypeDesc>description21</ItemTextsTypeDesc>
<ItemTextsLine>3</ItemTextsLine>
</ItemText>
<ItemText>
<ItemTextsType>type2</ItemTextsType>
<ItemTextsTypeDesc>description22</ItemTextsTypeDesc>
<ItemTextsLine>4</ItemTextsLine>
</ItemText>
</ItemTexts>
</Item>
</Items>
I run with xsl on each Item like :
<xsl:for-each select="Items/Item">
I need an example of how to group <ItemText>
by <ItemTextsType>
individually for each <Item>
so the outcome will be like :
For first <Item>
in this example :
type1
description11 description12
type2
description21
description22
For second Item
in this example :
type3
description31 description32
type2
description21
description22
of course I will arrange the outcome in a table like :
<table width="100%" border="1" style="display: block;">
<tbody>
<tr>
<td id="SelectedRowLinkageContents">
<table width="100%" dir="ltr">
<tbody>
<tr style="background-color: #507CD1; text-align: center">
<td colspan="3" style="font: bold; color: white">
Item1
</td>
</tr>
<tr>
<td style="height: 35px; font: bold; color: #507CD1;">
type1
</td>
</tr>
<tr>
<td>
desription11
</td>
</tr>
<tr>
<td>
desription12
</td>
</tr>
<tr>
<td style="height: 35px; font: bold; color: #507CD1;">
type2
</td>
</tr>
<tr>
<td>
desription21
</td>
</tr>
<tr>
<td>
desription22
</td>
</tr>
<tr>
<td>
desription23
</td>
</tr>
</tbody>
</table>
<table width="100%" dir="ltr">
<tbody>
<tr style="background-color: #507CD1; text-align: center">
<td colspan="3" style="font: bold; color: white">
Item2
</td>
</tr>
<tr>
<td style="height: 35px; font: bold; color: #507CD1;">
type1
</td>
</tr>
<tr>
<td>
desription11
</td>
</tr>
<tr>
<td>
desription12
</td>
</tr>
<tr>
<td style="height: 35px; font: bold; color: #507CD1;">
type2
</td>
</tr>
<tr>
<td>
desription21
</td>
</tr>
<tr>
<td>
desription23
</td>
</tr>
</tbody>
</table>
<table width="100%" dir="ltr">
<tbody>
<tr style="background-color: #507CD1; text-align: center">
<td colspan="3" style="font: bold; color: white">
Item3
</td>
</tr>
<tr>
<td style="height: 35px; font: bold; color: #507CD1;">
type1
</td>
</tr>
<tr>
<td>
desription11
</td>
</tr>
<tr>
<td>
desription12
</td>
</tr>
<tr>
<td style="height: 35px; font: bold; color: #507CD1;">
type2
</td>
</tr>
<tr>
<td>
desription21
</td>
</tr>
<tr>
<td>
desription23
</td>
</tr>
</tbody>
</table>
</td>
</tr>
</tbody>
</table>
The point is that there is separate grouping for each <Item>
into it's own <table>
and inside that <table>
there is groupping by <ItemTextsType>
I have tried something like
<xsl:key name="item-texts-type" match="ItemText" use="ItemTextsType" />
<xsl:for-each select="ItemTexts/ItemText[count(. | key('item-texts-type', ItemTextsType)[1]) = 1]">
<xsl:sort select="ItemTextsType" />
<tr>
<td style ="height:35px;font: bold; color:#507CD1;">
<xsl:value-of select="ItemTextsType" />
</td>
</tr>
<xsl:for-each select="key('item-texts-type', ItemTextsType)">
<tr>
<td>
<xsl:value-of select="ItemTextsTypeDesc" />
</td>
</tr>
</xsl:for-each>
</xsl:for-each>
but it only work on non repetitive nodes (if there were only one <Item>
it would work fine).
I can't change xml because it comes from customer .
Please help me , I need it ASAP .
Thank you !!!!
回答1:
It's still difficult to tell what the desired solution is due to some discrepancies - for instance, your input XML has 4 <Item>
elements, but your desired output only takes 3 of them into account. Additionally, several descriptions in your desired output do not match up with their expected location in the input XML document.
That said, if we focus on your stated desired solution:
"The point is that there is separate grouping for each
<Item>
into it's own<table>
and inside that<table>
there is groupping by<ItemTextsType>
"
...then this ought to get you in the right direction.
When this XSLT:

<xsl:strip-space elements="*" />
<xsl:key
name="kItemTextByType"

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