xml - Selecting value of child element -

-

why <xsl:value-of select="p"/> not resulting in output of xml source’s p element?

also, how can prevent xmlns="" appearing on result’s trans-unit elements?

thanks.

solution

p element value: per @larsh’s answer, namespace issue. added xmlns:custom = "http://ns.adobe.com/genericcustomnamespace/1.0/" declaration xsl:stylesheet element , used custom:p instead of p:

<xsl:value-of select="custom:p"/>

xmlns="": setting default namespace xmlns attribute on xsl:stylesheet element instead of manually on root element handles this.

new xslt in full:

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0"     xmlns:xsl="http://www.w3.org/1999/xsl/transform"     xmlns="urn:oasis:names:tc:xliff:document:1.2"     xmlns:vars = "http://ns.adobe.com/variables/1.0/"     xmlns:custom = "http://ns.adobe.com/genericcustomnamespace/1.0/"     exclude-result-prefixes="vars custom">      <xsl:output method="xml" encoding="utf-8" indent="yes"/>      <xsl:param name="file"/>     <xsl:param name="source-lang" select="'en-gb'"/>     <xsl:param name="target-lang"/>      <xsl:template match="/">         <xliff version="1.2">             <file original="{$file}" source-lanuage="{$source-lang}" target-language="{$target-lang}">                 <xsl:apply-templates select="//vars:sampledataset/*"/>             </file>         </xliff>     </xsl:template>      <xsl:template match="//vars:sampledataset/*">         <trans-unit id="{local-name()}">             <source xml:lang="{$source-lang}"><xsl:value-of select="custom:p"/></source>             <target xml:lang="{$target-lang}"></target>         </trans-unit>     </xsl:template>  </xsl:stylesheet>

why <xsl:value-of select="p"/> not resulting in output of xml source’s p element?

in template

<xsl:template match="//v:sampledataset/*">     <trans-unit id="{local-name()}">         <source xml:lang="{$source-lang}"><xsl:value-of select="p"/></source>

the context node child of <v:sampledataset>, such <variable1>. in source xml, latter has <p> element children in namespace identified uri http://ns.adobe.com/genericcustomnamespace/1.0/. because <p> has no namespace prefix, uses default namespace, established nearest ancestor has default namespace declaration. 

<v:sampledatasets  ... xmlns="&ns_custom;">

however xslt asking p elements in no namespace. hence lack of output.

also, how can prevent xmlns="" appearing on result’s trans-unit elements?

you can't guarantee how namespace declarations appear in serialized output. however, can specify namespace each element in. since want <trans-unit> elements in oasis namespace, need specify in xslt; , since have ancestor in output xml has oasis namespace default namespace, may serialized no namespace prefix , no namespace declaration attribute. can tell xslt output <trans-unit> elements in oasis namespace same way did <xliff> elements:

   <trans-unit xmlns="urn:oasis:names:tc:xliff:document:1.2" id="{local-name()}">

that put trans-unit elements correct namespace in result xml, important thing downstream processing (and isn't correct @ moment). namespace declarations in result xml nice, that's not guaranteed. however, there details placing namespace nodes don't remember, maybe else can give better answer on that.

i have seen instructions on running cron in advanced template, cant figure out how on basic template. have following controller in basic controllers folder. <?php namespace app\controllers; use yii\console\controller; /** * cron controller */ class croncontroller extends controller { public function actionindex() { echo "cron service runnning"; } public function actionmail($to) { echo "sending mail " . $to; } } i have navigated root of application , tried these comands yii cron php yii cron im getting unknown comand "cron" i know old question failed find actual answer this. if @ code yii exec file you'll notice requires /common/config/aliases.php file console/config/main.php. can naturally change these or copy on these advanced template. hope solves problem wanting same thing.

mercurial graft feature, can it copy? -

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
