attributes - XSLT 1.0: how to get print of first non-empty value of two (see inside) -


i want first non-empty value of 2 , put "value" attribute of text input. so, do:

<input type="text">   <xsl:attribute name="value">     <xsl:choose>       <xsl:when test="some/@attr != ''">         <xsl:value-of select="some/@attr" />       </xsl:when>       <xsl:otherwise>         <xsl:value-of select="some/another/@attr" /> <!-- non-empty, -->       </xsl:otherwise>     </xsl:choose>   </xsl:attribute> </input>

question is: there way make less lines of code?.. maybe, that: <input type="text" value="some/@attr or some/another/@attr" /> or something?.. in, say, perl: my $val = 0 || 5;

thanks in advance help

upd xslt 1.0

the relay magic in answer form @martin honnen. enhancement,to make little shorter can use "attribute value templates"

<input type="text" value="{some/@attr[. != ''] | some/another/@attr}"> </input>

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
