Copy specific node and nodes that used in specific node children

TerTer · May 30th, 2012, 07:27 AM

Hello,
i'm new to xslt, just using it for 2weeks not. And now i'm stuck.

So first examples:
Input:

Code:

    <?xml version="1.0" encoding="UTF-8"?>
    <xmi:XMI xmlns:namespace1="http://namespace" xmlns:xmi="http://www.omg.org/spec/XMI/20110701" attribute1="some1" xmlns:M="mOptions" xmlns:N="nOptions">
     
     <namespace1:mode name="Main">
     <node0>0</node0>

    <namespace1:parm name="node1" attribute2="some2" namespace1:type="type1"> 
    	<child1 name="a" id="1"/>
    	<child2 name="b" id="2"/>
    </namespace1:parm>

    <element name="node2" attribute2="some3" namespace1:type="type2"> 
    	<child6 name="a6" id="6"/>
    	<child7 name="b7" id="7"/>
    </element>

    <node id="55"/>

    </namespace1:mode>
 
    <M:extra1 id="1"/>
    <M:extra2 id="2"/>
    <M:extra6 id="6"/>
    <M:extra7 id="7"/>

    </xmi:XMI>

Wanted output:

Code:

    <?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmlns:namespace1="http://namespace" xmlns:xmi="http://www.omg.org/spec/XMI/20110701" attribute1="some1" xmlns:M="mOptions" xmlns:N="nOptions">
     
    <namespace1:parm name="node1" attribute2="some2" namespace1:type="type1"> 
        	<child1 name="a" id="1"/>
        	<child2 name="b" id="2"/>
    </namespace1:parm>

    <M:extra1 id="1"/>
    <M:extra2 id="2"/>
</xmi:XMI>

So what i need is to copy a specific node, in this example name=node1 and namespace1:type=type1, then remove all <M:extra.../> nodes that are not used in specific node. It can be that node will be name="node2" and namespace1:type=type2, but node name should become namespace1:parm.
Name will differ, but figure out that i can read the name from options file into a variable.

For now i'm trying to clean up the xmi using:

Code:

<xsl:template match="xmi:XMI|*[@namespace1:type='type1']">
        <xsl:copy>
            <xsl:for-each select="@*">
                <xsl:attribute name="{name(.)}">
                    <xsl:value-of select="."/>
                </xsl:attribute>
            </xsl:for-each>
            <xsl:apply-templates/>
        </xsl:copy>
    </xsl:template>

but getting:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmlns:namespace1="http://namespace"
         xmlns:xmi="http://www.omg.org/spec/XMI/20110701"
         xmlns:M="mOptions"
         xmlns:N="nOptions"
         attribute1="some1">0<namespace1:parm name="node1" attribute2="some2" namespace1:type="type1"/>
</xmi:XMI>

somehow i get 0 and do not get children of wanted node. Have no clue how to clean up/keep some <M:extra.../> tags yet.

When i try

Code:

<xsl:template match="*">
        <xsl:copy>
            <xsl:for-each select="@*">
                <xsl:attribute name="{name(.)}">
                    <xsl:value-of select="."/>
                </xsl:attribute>
            </xsl:for-each>
            <xsl:apply-templates select="xmi:XMI|*[@namespace1:type='type1']"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="xmi:XMI|*[@namespace1:type='type1']">
        <xsl:copy>
            <xsl:for-each select="@*">
                <xsl:attribute name="{name(.)}">
                    <xsl:value-of select="."/>
                </xsl:attribute>
            </xsl:for-each>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

im getting:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmlns:namespace1="http://namespace"
         xmlns:xmi="http://www.omg.org/spec/XMI/20110701"
         xmlns:M="mOptions"
         xmlns:N="nOptions"
         attribute1="some1">some1<namespace1:mode name="Main">
      <namespace1:parm name="node1" attribute2="some2" namespace1:type="type1">node1some2type1<child1 name="a" id="1"/>
         <child2 name="b" id="2"/>
      </namespace1:parm>
   </namespace1:mode>
   <M:extra1 id="1"/>
   <M:extra2 id="3"/>
   <M:extra6 id="6"/>
   <M:extra7 id="7"/>
</xmi:XMI>

Somehow i'm getting node1some2type1 in between my specific node and some1<namespace1:mode name="Main"> and children and still do not have a clue how to remove <M:extra...> thinking maybe can be done with another template mapping used children or something.

After few tries got this

Code:

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

    <xsl:template match="namespace1:mode">
        <xsl:call-template name="RecursiveCopy"/>
    </xsl:template>

    <xsl:template name="RecursiveCopy">
        <xsl:for-each select="*">
            <xsl:if test="attribute()=$type">
                <xsl:element name="namespace1:parm">
                     <xsl:apply-templates select="@*|node()"/>
                </xsl:element>
            </xsl:if>
            <xsl:if test="not(attribute()=$type)">
                <xsl:call-template name="RecursiveCopy"/>
            </xsl:if>
        </xsl:for-each>
    </xsl:template>

After applying it i get this:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmlns:namespace1="http://namespace"
         xmlns:xmi="http://www.omg.org/spec/XMI/20110701"
         xmlns:M="mOptions"
         xmlns:N="nOptions"
         attribute1="some1">
   <namespace1:parm name="node2" attribute2="some3" namespace1:type="type2">
      <child6 name="a6" id="6"/>
      <child7 name="b7" id="7"/>
   </namespace1:parm>
   <M:extra1 id="1"/>
   <M:extra2 id="3"/>
   <M:extra6 id="6"/>
   <M:extra7 id="7"/>
</xmi:XMI>

now i need to remove <M:extra../> tags that are not used in so need to remove <M:extra1 id="1"/> and <M:extra2 id="3"/> as id 6-7 is used in namespace1:parm.

Also i still need if there is only namespace1:parm and xmi:XMI left to merge xmi:XMI with my tag copying all namespaces and attributes.

Code:

..
<xmi:XMI namespace2 attribute2>
<namespace1:parm attribute1 namespace1>
...
</namespace1:parm>
</xmi:XMI

need to get

Code:

..
<namespace1:parm namespace1 attribute1 namespace2 attribute2>
...
</namespace1:parm>
