Google webmaster tool detects errors in sitemap?

Question

I have a sitemap that looks like this :

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:geo="http://www.google.com/geo/schemas/sitemap/1.0">

<url>

<loc>http://www.MyApp.se</loc>
<lastmod>2012-06-29</lastmod>
<changefreq>daily</changefreq>
<priority>1.0</priority>

<lastmod>2012-06-28</lastmod>
<changefreq>weekly</changefreq>
<priority>0.5</priority>
</url>
</urlset>

And this is my Robo.txt :

User-agent: *
Disallow:
Sitemap: <http://www.MyApp.se/Site/Sitemap/>

The problem is that in Google Webmaster tool I get the following errors :

1
Warning
Invalid XML-tagg
This tag could not be identifyed.
**Problems :** 6
Tag: url
**Row :** 7
Tag: url
13
Tag: url
**Row :** 19

2
Warning 
Webadress blocked by robots.txt.
Sitemap contains webadresses that is blocked by robots.txt.
**Problems :** 12
Value : http://www.MySite.se
Value: http://www.MySite.se/Ad/Detail?id=283
Value: http://www.MySite.se/Ad/Detail?id=284

Why? I have constructed the sitemap according to guides on internet?

OK, the <url> tags are all over the place. Everything from the opening <loc> tag to the closing </priority> tag for each website page must be enclosed within a set of <url> tags. See amended code below:

<?xml version="1.0" encoding="UTF-8"?>
<urlset
xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Just to tidy up your robots.txt file, make it look as below. Make sure the Sitemap declaration links to the location of your sitemap.xml file:

User-agent: *
Sitemap: http://point-this-to-your-sitemap.xml

There's also no need for an empty Disallow declaration.

This is the basic structure I follow for the websites that I develop, so it should be fine!

Looking at the beginning of your file, you seems to have a problem with XML tags, you seem to have forgotten a after the first bloc. You have :

     <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:geo="http://www.google.com/geo/schemas/sitemap/1.0">

    <url>

    <loc>http://www.MyApp.se</loc>
    <lastmod>2012-06-29</lastmod>
    <changefreq>daily</changefreq>
    <priority>1.0</priority>
    <url>

    <loc>http://www.MyApp.se/Ad/Edit</loc>

[...]

And you should have :

     <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:geo="http://www.google.com/geo/schemas/sitemap/1.0">

    <url>        
    <loc>http://www.MyApp.se</loc>
    <lastmod>2012-06-29</lastmod>
    <changefreq>daily</changefreq>
    <priority>1.0</priority>
    </url>

    <url>
    <loc>http://www.MyApp.se/Ad/Edit</loc>

[...]

I think you have the same problem somewhere else in your code. You could try to use an XML editor to verify.
