xml - xslt result-document overwrite or skip file with duplicate uri -


is there way make xsl:result-document overwrite or skip files when output files have duplicate uri ? think don't have provide example. have database duplicate entries in it. know can put id , remove id names of 60000 files

best regards.

it seems xslt 3.0 can catch error write output uri twice using xsl:try/xsl:catch, given stylesheet

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform"     xmlns:xs="http://www.w3.org/2001/xmlschema"     xmlns:math="http://www.w3.org/2005/xpath-functions/math"     xmlns:err="http://www.w3.org/2005/xqt-errors"     exclude-result-prefixes="xs math"     version="3.0">      <xsl:mode streamable="yes"/>      <xsl:output method="text"/>     <xsl:strip-space elements="*"/>      <xsl:template match="/">         <xsl:apply-templates select="copy-of(root/record)" mode="result"/>     </xsl:template>      <xsl:template match="record" mode="result">         <xsl:try>             <xsl:result-document href="{fname}.txt" method="text">                 <xsl:value-of select="* except fname" separator=","/>             </xsl:result-document>             <xsl:catch errors="err:xtde1490">                 <xsl:message select="'attempt write more once ', fname"/>             </xsl:catch>         </xsl:try>     </xsl:template>  </xsl:stylesheet>

and input like

<?xml version="1.0" encoding="utf-8"?> <root>     <record>         <fname>result1</fname>         <foo>1</foo>         <bar>a</bar>     </record>     <record>         <fname>result2</fname>         <foo>2</foo>         <bar>b</bar>     </record>     <record>         <fname>result1</fname>         <foo>1</foo>         <bar>a</bar>     </record> </root>

saxon 9.8 ee processes input streaming , writes 2 result files while catching error when trying write second time result1.txt when processing third record.

as @michaelkay's comment implementation dependency duplicates caught, agree that, if matters avoid can replace 

<xsl:template match="/">     <xsl:apply-templates select="copy-of(root/record)" mode="result"/> </xsl:template>

with use of xsl:iterate

<xsl:template match="/">     <xsl:iterate select="root/record">        <xsl:apply-templates select="copy-of()" mode="result"/>     </xsl:iterate> </xsl:template>

that way think sequential processing done.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
