all- new xslt. use understand basic.

the xml

    <root>        <article>           <bullettext>10,00 </bullettext>           <bullettext>8,00 </bullettext>         </article>        <article>           <something>some text</something>        </article>        <article>           <corpsdetexte>bulgaria</corpsdetexte>            <bullettext>15,0 </bullettext>           <bullettext>10,0 </bullettext>         </article>        <article>           <corpsdetexte>somaialia</corpsdetexte>           <bunk>test</bunk>               <bullettext>15,1</bullettext>              <bullettext>10,2</bullettext>              <bullettext>20,3</bullettext>              <bullettext>25,4</bullettext>              <bullettext>30,5 </bullettext>         </article>     </root>

xslt 1

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">      <xsl:strip-space elements="*"/>      <xsl:output indent="yes"/>        <!-- copy elements -->      <xsl:template match="node()">         <xsl:copy>             <xsl:apply-templates select="node()"/>         </xsl:copy>     </xsl:template>      <!-- process first bullet text  element under template -->     <xsl:template match="bullettext[not(preceding-sibling::*[1][name()='bullettext'])]">         <!-- find element want stop @ -->         <xsl:variable name="stop" select="./following-sibling::*[name() != 'bullettext'][1]"/>         <list>             <xsl:choose>                 <!-- first, simple case:  there's no element have stop @ -->                 <xsl:when test="not($stop)">                     <xsl:apply-templates select="." mode="item"/>                     <xsl:apply-templates select="./following-sibling::bullettext" mode="item"/>                 </xsl:when>                  <!-- required -->                 <!-- transform elements between start , stop index items -->                 <xsl:otherwise>                     <xsl:variable name="start_index" select="count(preceding-sibling::*) + 1"/>                     <xsl:variable name="stop_index" select="count($stop/preceding-sibling::*)"/>                     <xsl:apply-templates select="../*[position() &gt;= $start_index  , position() &lt;= $stop_index]" mode="item"/>                 </xsl:otherwise>             </xsl:choose>         </list>     </xsl:template>      <xsl:template match="bullettext" />       <xsl:template match="bullettext" mode="item">         <item>             <xsl:value-of select="."/>         </item>     </xsl:template>   </xsl:stylesheet>

xslt 2 _ notice missing 'otherwise in choose.

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">      <xsl:strip-space elements="*"/>      <xsl:output indent="yes"/>        <!-- copy elements -->       <xsl:template match="node()">         <xsl:copy>             <xsl:apply-templates select="node()"/>         </xsl:copy>     </xsl:template>      <!-- process first bullet text  element under template -->     <xsl:template match="bullettext[not(preceding-sibling::*[1][name()='bullettext'])]">         <!-- find element want stop @ -->         <xsl:variable name="stop" select="./following-sibling::*[name() != 'bullettext'][1]"/>         <list>             <xsl:choose>                 <!-- first, simple case:  there's no element have stop @ -->                 <xsl:when test="not($stop)">                     <xsl:apply-templates select="." mode="item"/>                     <xsl:apply-templates select="./following-sibling::bullettext" mode="item"/>                 </xsl:when>                  <!-- required -->                 <!-- transform elements between start , stop index items -->             </xsl:choose>         </list>     </xsl:template>      <xsl:template match="bullettext" />       <xsl:template match="bullettext" mode="item">         <item>             <xsl:value-of select="."/>         </item>     </xsl:template>   </xsl:stylesheet>

both give same result

<root>     <article>         <list>             <item>10,00 </item>             <item>8,00 </item>         </list>     </article>     <article>         <something>some text</something>     </article>     <article>         <corpsdetexte>bulgaria</corpsdetexte>         <list>             <item>15,0 </item>             <item>10,0 </item>         </list>     </article>     <article>         <corpsdetexte>somaialia</corpsdetexte>         <bunk>test</bunk>         <list>             <item>15,1 </item>             <item>10,2 </item>             <item>20,3 </item>             <item>25,4 </item>             <item>30,5 </item>         </list>     </article> </root>

what value of otherwise in example. , why work without otherwise?

note: answer question posed. sorry not have link

your input not contain bullettext nodes. therefore, 3 templates matching bullettext never applied , makes no difference contain.

however, input such as:

<root>     <article>         <bullettext>alpha</bullettext>         <bullettext>bravo</bullettext>         <text>charlie</text>         <bullettext>delta</bullettext>     </article> </root>

you see difference: first xslt return:

<?xml version="1.0" encoding="utf-8"?> <root>    <article>       <list>          <item>alpha</item>          <item>bravo</item>       </list>       <text>charlie</text>       <list>          <item>delta</item>       </list>    </article> </root>

while second 1 produce only:

<?xml version="1.0" encoding="utf-8"?> <root>    <article>       <list/>       <text>charlie</text>       <list>          <item>delta</item>       </list>    </article> </root>

java - UML - How would you draw a try catch in a sequence diagram? -

-
Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
