Mixed Transformer

This example uses SAXDOMIX to apply an XSLT transformation to each DOM tree created during the mixed SAX-DOM parsing of an XML document. All SAX events that aren't used to build DOM trees are copied to the resulted XML document.

We have the following MixedTransformer.xml file:

    <?xml version="1.0" encoding="utf-8"?>

    <root>
        <elem1 wantDOM="true">
            <!-- comment1 -->
            <elem11>text11</elem11>
            <elem12><![CDATA[cdata12]]></elem12>
            <elem13>
                <elem131/>
                <elem132/>
            </elem13>
            <?proc1 data?>
        </elem1>
        <elem2>
            <!-- comment2 -->
            <elem21 wantDOM="true">data21</elem21>
            <elem22 wantDOM="true"><![CDATA[cdata22]]></elem22>
            <elem23>text23</elem23>
            <?proc2 data?>
        </elem2>
    </root>

We want the apply the transformation instructions contained by a file called MixedTransformer.xsl to all XML fragments that start with an element that has a wantDOM="true" attribute. The content of MixedTransformer.xsl is included below:

    <?xml version="1.0" encoding="utf-8"?>

    <xsl:stylesheet version="1.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

        <xsl:output cdata-section-elements="elem12 elem22"/>

        <xsl:template match="elem1">
            <NEW-elem1>
                <xsl:comment> NEW<xsl:value-of select="comment()"/></xsl:comment>
                <NEW-elem11>NEW <xsl:value-of select="elem11"/></NEW-elem11>
                <NEW-elem12><xsl:value-of select="concat('NEW ', elem12)"/></NEW-elem12>
                <NEW-elem13>
                    <NEW-elem131/>
                    <NEW-elem132/>
                </NEW-elem13>
                <xsl:processing-instruction name="NEW-proc1"> NEW <xsl:value-of
                    select="processing-instruction()"/></xsl:processing-instruction>
            </NEW-elem1>
        </xsl:template>

        <xsl:template match="elem21">
            <NEW-elem21>NEW <xsl:value-of select="."/></NEW-elem21>
        </xsl:template>

        <xsl:template match="elem22">
            <NEW-elem22><xsl:value-of select="concat('NEW ', .)"/></NEW-elem22>
        </xsl:template>

    </xsl:stylesheet>

Execute this command:

    java com.devsphere.examples.xml.saxdomix.MixedTransformer
    -xsl MixedTransformer.xsl -in MixedTransformer.xml

You'll get the following output:

    <?xml version="1.0" encoding="UTF-8"?>
    <root>
        <NEW-elem1>
            <!-- NEW comment1 -->
            <NEW-elem11>NEW text11</NEW-elem11>
            <NEW-elem12>NEW cdata12</NEW-elem12>
            <NEW-elem13>
                <NEW-elem131/>
                <NEW-elem132/>
            </NEW-elem13>
            <?NEW-proc1 NEW data?>
        </NEW-elem1>
        <elem2>
            <!-- comment2 -->
            <NEW-elem21>NEW data21</NEW-elem21>
            <NEW-elem22>NEW cdata22</NEW-elem22>
            <elem23>text23</elem23>
            <?proc2 data?>
        </elem2>
    </root>
